Today we successfully deployed the new forensic experiment, recovered both Benthic Boundary Layer (BBL) platform and the IOS hydrophone array. All operations were in the Strait of Georgia. Also, today it was decided not to redeploy the new hydrophone systems (ONC Innovations) that were recovered two days earlier. The hydrophones will require more time to fine-tune and will be re-deployed in 2014.

A very successful cruise aboard the R/V Falkor has come to an end. The ship docked in Victoria at Ogden Point around 0830 yesterday morning, and we spent the day off-loading equipment and cleaning the labs. The final day of operations was spent at Tully Canyon where we did two extensive survey dives to examine benthic life in the low-oxygen environment. In the evening, we had a barbecue all together on the upper deck of the ship to celebrate the end of the cruise. Many thanks to all those who contributed to make this expedition possible: Schmidt Ocean Institute, the crew of the R/V Falkor, the ROPOS team, our visiting scientists, and the staff supporting us on shore.
Operations in Barkley Canyon finished at noon today. The last dive, the 600 m transect, completed successfully after a couple of minor delays overnight. We found quite a bit of kelp which was sampled, in addition to sponges and anemones. Now we are doing a multibeam survey and looking forward to two dives starting at midnight at Tully Canyon, a short steam away across the U.S. border.

Dive R1655, the 300 and 400 metre deep transects of Barkley Canyon, took place overnight. It was very interesting - especially so for those of us who have seen the Ocean Networks Canada sites in Barkley Canyon many times - because of the rugged topography and prevalence of rocks and pebbles that we don't see further down in the canyon. Kelp found, samples taken, and we are now underway to the 1500 m transect site.

The tether retermination went very quickly, however before we could get back in the water, a power issue with the telemetry can also needed to be resolved. ROPOS worked through the night, allowing us to start Dive R1564 early this morning. In that dive we completed a 200 m deep transect of the head of Barkley Canyon. We encountered a region where fragile pink sea urchins were incredibly abundant. We did suction samples of the sediment surface, push cores and gathered sea urchins and sea cucumbers for analysis. Dive R1655: 300 m and 400 m transects will be starting in a few hours.
Read more in Daily Log - September 14, 2013
The first transect at 2000 m resulted in some interesting samples including sea pens, sea cucumbers and an anenome for which we currently have no identification. Unfortunately, last night on recovery there was a kink in the ROV tether which has forced us to pause survery operations to reterminate the umbilical. We hope to be diving again early this afternoon.

This morning we finished the last instrument/experiment deployment dive of the cruise. Next on the programme are visual and sampling transects at staggered depths across Barkley Canyon to study the relationship between oxygen levels and observable fauna. We are at bottom, just about to start the first transect at 2000 m, below the oxygen minimum zone (Dive 1653).

Dive 1651 at Barkley Canyon POD 3 has just started. In this dive, we will be deploying the first algae treatment of a sediment enrichment experiment. We will be distributing phytodetritus within the frames that we placed in view of the camera yesterday. While waiting for the treatment to settle, we will survey at Wallyland and return to the Coral Cliff to recover the second ADCP.

The operations at Clayoquot Slope (formerly OPD 889) went well: we swapped the CTD for a CTD-O2, we exchaned SCIMPI's data logger and recovered the broadband seismometer auxiliary platform. Now, the Falkor has arrived at Barkley Canyon, and we are getting ready for a morning dive to install a sonar at Wallyland, clean the crawler and deploy the first stage of a sediment enrichment experiment at POD 3. The dive will be starting around 0800.
We have completed all our work in Saanich Inlet and the Strait of Georgia: push cores have been taken, 2 cliff climbs and a transect were completed, the Buoy Profiling System is connected and organisms have been sampled. We are now heading offshore to Clayoquot Slope where we will first perform a navigation system calibration and followed by instrument operations starting early Monday morning.

The first dive of Leg 2 of the Falkor cruise has started! We are in Saanich Inlet, starting a visual transect of Patricia Bay. The purpose of this dive is to discover the distribution of flatfish in relation to depth and oxygen levels. We will be collecting live samples of these fish for further analysis in the lab.
Read more in Daily Log - September 7, 2013
Today the R/V Falkor set sail from Ogden Point, kicking-off Leg 2 of the "Open Ocean to Inner Sea expedition". Preliminary tasks include several benthic surveys in Saanich Inlet, along with the physical connection of the new Buoy Profiler System recently installed in Saanich Inlet to the VENUS node in Patricia Bay.

August 31, 15:00PDT Update
Today the R/V Falkor pulled into the Esquimalt Harbour and the first leg of the ONC-SOI 2013 joint expedition come to a conclusion. We packed up our personal possessions, cleaned the laboratories, and dismantled the scientific gear. By mid-afternoon the aft deck was clear and a truck-load of equipment was return to UVic’s Marine Technology Centre. Tomorrow, the loading of ROPOS begins.
Prior to our most recent exposure to this special oceanographic system, MVP is most often a reference to Most Valuable Player. It is an award, often handed out annually in a sports league, to a player who has contributed the most in a team’s effort to achieve their goals. The MVP on this cruise was, in both senses, the Moving Vessel Profiler.

As the penultimate science day, we are really ticking off the boxes of what needs to be accomplished. Yesterday we did a little run along the coastal front next to Vancouver Island. We then zig-zagged yet again along the shelf break, and finally we did a nice tidal time series over the Zeppelin Bank and across the Tully canyon over a flood tide. The final MVP survey tomorrow will be relatively short (12 hours), before we bang off our last CTD and head for home.
Read more in Daily Log - Aug 29, 2013
Today the edits to the plan were minor, and we have started our final push. The weather is grey, with low clouds, irregular seas, and cool temperatures. The forecast calls for an increase in the SE wind. The MVP remains in the water nearly all day, with periodic checks on the fish to inspect for kelp and wear. Our adaptive sampling has a few days left to map some of the key features one last time.

The bumpy sea abated through the night, and by morning, the winds were light and the sea a confused wash of old and dying waves. We steam along at our preferred MVP speed of eight knots, and sample with particular purpose. The MVP is used to find exact locations across the continental shelf front for our final set of CTD casts. We are very pleased with these samples. By the end of the day, we have started a marathon of an MVP survey, very likely our last hurrah. If we never give up, luck will find us.
Read more in Daily Log - Aug 27, 2013
There has been a standing forecast the last couple of days for gale force winds. They started to build last night, and outside of Barkley Sound, we are seeing a steady 30 knots. Both the MVP and CTD seem game at first, so the sampling program should not be affected, but we will take a little more care with deck operations.
Read more in Daily Log - Aug 26, 2013
Today a plan for the remainder of the cruise was prepared. We'll see how long it lasts, events change regularly at sea. But it’s a workable plan and includes the remaining cruise objectives. The adaptive science is relentless and gives me no quarter.

We complete the second MVP survey along the centre of Tully Canyon, ending near the NEPTUNE Folger site and Bamfield. We let Stephane Gauthier off at Bamfield, so he can get ready for another cruise. We conduct a multi-beam survey of Folger pinnacle, and start the third MVP survey. The oxygen story is both coming into focus and confirming some recent findings by Bill Crawford about the presence of very low oxygen water in the central shelf west of Vancouver Island. At the end of the day, rather dazed and less confused, we see bubbles.

Late in the evening Tuesday we started the first moving vessel profiler (MVP) survey. It was completed this morning, and has given us some food for thought. The middle of the day was devoted to calibrating the ship’s new ultra-short baseline (USBL) transponder, before we started an eagerly anticipated MVP transect up the Tully Canyon.

The day has been a very typical oceanographic sampling day, dominated by “classic hydrography”, which is the measurement of water properties as a function of depth at fixed stations across the ocean. Continuing from yesterday, we completed the initial CTD and Rosette survey, including portions of the Barkley Canyon and La Perouse C lines.
Read more in Daily Log - Aug 20, 2013
This morning at 0800 we arrived at the entrance to Juan de Fuca Strait. A light fog, but relatively calm seas. The morning briefing on the bridge confirms today’s simple schedule: a final configuration of the MVP and then we start an intense CTD/Rosette survey.

We have now completed our expedition aboard the R/V Thompson and demobilized from ship. We're looking forward to our next expedition about the R/V Falkor, beginning August 17.
We are homeward bound! The R/V Thompson is presently in the Strait of Juan de Fuca, on its way to port in Seattle. Our scheduled ETA is 1100, June 25th, following which trucks will arrive to load our gear, and the ONC staff will return to Victoria via the Clipper. The last stop at Clayoquot Slope (formerly ODP 889) was short, but we nevertheless did 2 dives. We recovered the CSEM instrument, investigated a vent hole and visited the SHRIMPI and SCIMPI instruments.
Dive M0017 has come and gone. We deployed four instruments at Cascadia Basin (formerly ODP 1027), our deepest site at 2660 m. We are now steaming to Clayoquot Slope (formerly ODP 889) to recover the CSEM instrument, investigate a vent hole, and collect data from SCIMPI and Shrimpi instruments. This will be our last stop of the cruise before returning to port in Seattle.
Endeavour is behind us and we have moved on to Cascadia Basin (formerly ODP 1027). At this site, we will deploy a low-frequency (LF) hydrophone, a bottom pressure recorder (BPR) experiment, an acoustic Doppler current profiler (ADCP) and a conductivity-temperature-depth (CTD) instrument with an oxygen sensor. Dive M0017 has just started. The ROV and the instrument package on the ship's wire are descending and will be on bottom shortly.
The cable spool was recovered this morning and is now on deck. Dive M0016 at Main Endeavour Field is underway. The deployment of the Remote Access water Sampler (RAS) just came to a successful end. Next, we are taking some tubeworm samples, and then recovering the ROV. Next stop, Cascadia Basin (formerly, ODP 1027).
We have moved back to the Endeavour Mothra site to recover the Mothra cable and LOCO cable laying system. Dive M0015 has just begun. This afternoon, we dove at the Endeavour North location (RCM-North) to continue the diagnosis of the communications failure. We determined that plugging the existing cable into a different node port did not bring the site online. After performing several other tests, it is suspected that the cable might be at fault for the problem.
At the end of Dive M0011, the ROV tether caught on some rocks around the base of Grotto which necessitated maintenance after recovery to the spooling system. Dives M0012 and M0013 also had to end early due to related problems. The deployment of the Remote Access water Sampler (RAS) was interrupted. We are taking a break from Main Endeavour Field to continue the diagnosis of the communications issues at the RCM-North site, but will return later to finish MEF operations.
Dive M0011 is coming to an end. We need to recover the ROV in order to reset the gas tights for RAS (remote access water sampler) deployment. In the last day, we completed Tempo-Mini's deployment, a visual survey of Grotto for photogrammetry, deployment of temperature loggers near Tempo-Mini and we designed and lowered new bio-buckets for tubeworm collection, which will occur on the next dive. RAS will be lowered on the ship's wire this morning.
Dive M0011 has now been underwater for nearly 40 hours. The crew, ROV pilots, science and engineering teams are working hard to keep up with 24 hour operations. Tempo-Mini deployment is ongoing; the ROV is getting ready to position the instrument on Grotto. Today is a beautiful sunny day and we are still fortunate with calm seas.
Dive M0011 ongoing and proceeding well. Following the last update, BARS has been successfully deployed and water samples and temperature profiles for COVIS were completed. We also took tubeworm samples from North Tower and gas tights for BARS calibration. At the time of this writing, Tempo-Mini is waiting for deployment on the ship's wire and will be placed next. Other upcoming tasks: temperature logger replacement, photogrammetry survey, short-period seismometer and auxilliary platform deployment, and further sampling.
Dive M0011 at Main Endeavour Field in progress. Instruments are being lowered to the seafloor on a specially built platform on the ship's wire and guided to the bottom by the ROV. The first load included the 600 kHz ADCP (Acoustic Doppler Current Profiler) and BARS (Benthic and Resistivisty Sensors) vent probe. Early this morning, the ADCP was deployed. We are currently in the process of placing BARS in a vent on the Grotto crown.
We are moving on station to begin dive operations at Main Endeavour Field. In the next two days, we will deploy RAS, BARS, Tempo-Mini, a 600kHz ADCP, temperature loggers, and do biological and visual sampling. We anticipate being on bottom around midnight tonight, PDT, but it will still take us some time to begin operations, so the first deployments will start in the early morning. We left RCM-North without successfully diagnosing the failure. The spare junction box did not resolve the issue; we will return later in the cruise.
We have moved on to the RCM-North site to diagnose the communications failure at that location. Dive M0010 is in progress. The first test is to evaluate the functioning of the junction box. We have lowered a spare instrument platform on the ship's wire and we will be attempting to connect it shortly. The attempts to mate the connector to LOCO on previous dives were not successful and therefore we were unable to lay the Mothra-Midpoint cable up to now.
Dive M0009 in progress. We attempted to bring LOCO, the cable laying system, up to 250 m in order to try to mate the connector to the cage. We were able to plug it in, but the connector would not stay mated. The ROV is presently on the way back to the bottom with the spool. We will not be able to lay the cable at this time, however, we are in contact with Oceaneering and they are working on a solution. In the meantime, if we can't lay the cable, we intend to go to RC-North to diagnose the failure at that site.
Dive M0008 is underway. The goal of this dive is to bring the cable layer (LOCO) attached to the Mothra cable spool up to a shallower depth at which we hope it will be possible to mate the connector between the cage and LOCO. Our tests on Dive M0007 revealed that the dummy connectors could be successfully mated between 250 and 500 m depth. When connected, we will return the spool to the seafloor and begin the Mothra-Midpoint cable lay. Once started (at the earliest, Sunday morning PDT), the lay will take approximately 12 hours to complete.
More dive woes overnight. We had to do an emergency recovery because the pan & tilt was damaged on the main HD camera during dive M0006 before the connection to LOCO could be established. Weather is still co-operating. All hoping for good news later today.
The ROV is back on deck again. We were unable to start the cable lay because of problems mating the connector to power the cable laying system. The ROV team is working on the issue, and we should be diving again soon.
We are beginning the Mothra-Midpoint cable lay. The heading required for the cable lay might interfere with satellite communications from the ship. (There is a small "block zone" for visibility of the satellite with the antenna on the ship.) If there are outages in the live feed, don't panic and please check back later!
Dive M0005 is now underway. The end of the cable has been connected to the Mothra Instrument Platform; cable lay to Midpoint upcoming. The last operation of Dive M0004 was to recover four acoustic releases which will sit between the cage and the spool to provide a release mechanism should the cable lay be interrupted. M0004 completed around 04:30 this morning.
Dive M0004 is coming to an end. The spool of cable for the Mothra-Midpoint cable lay has been deployed on the ship's wire and readied by the ROV for the cable lay. We will perform the lay on the next dive overnight and into the morning. Weather is perfect for operations: flat seas.
Dive M0003 has just started; dive objective to lay Mothra to Midpoint cable. M0002 was another short dive, following which several issues were resolved overnight with the ROV and navigation. The weather and seastate are perfect for cable laying so we are optimistic about upcoming operations.
We are currently at Mothra running a CTD. A first test dive (M0001) with the ROV revealed some minor problems which got sorted out and we are about to conduct another test before we go on the first science dive (Mothra).
We are approximately 2 hours away from Endeavour, heading to Mothra for our first operations. We will start with a CTD cast at the site, and then evaluate weather conditions for starting the Mothra to Midpoint cable lay. Winds have been 15-20 kn this morning with a approximately 2 m seas.
We are currently underway, steaming through Puget Sound en route to the Strait of Juan de Fuca. From there, we will transit to the Endeavour site where we will start our maintenance operations. The ROV has completed two important tests: a successful wet test at the dock in Seattle overnight, and a navigation test this afternoon. We are taking advantage of the 28 hour transit to finish organizing ourselves onboard for the upcoming operations.
Mobilization is in progress aboard the R/V Thompson for the Ocean Networks Canada June Cruise. We anticipate being ready to sail Tuesday morning. The Oceaneering Millenium ROV is onboard and nearly ready for wet test. All hands are busy with setup of video transmission, network systems, instrument preparation, and securing the deck for transit. The rest of the science party will be arriving later this afternoon on the Clipper from Victoria. Stay tuned!
Welcome to the R/V Thompson cruise scheduled for June 11 to 26th, 2013. We are currently mobilizing in Seattle, Washington, with crew and visiting researchers arriving from around the world. This expedition will feature the Oceaneering ROV “Millenium,” operated by Canpac Divers. Check out our live video to see the "Millenium," and stay tuned for updates in this space!
No Expedition Operations at this time.
Watch for our Thompson expedition - June 9 to June 26.
Our expedition aboard the CCGS Tully has concluded and we are now demobilizing from ship at the Institute of Ocean Sciences dock in North Saanich, BC.
We are currently transiting from the Strait of Georgia to Saanich Inlet. We will be diving this morning at 1000 to complete a series of cliff surveys in Squally Reach. This afternoon we will shift to our Saanich Node site for one final dive before coming alongside.
This morning we are sitting off the mouth of the Fraser River at our Delta Dynamics Laboratory site. We will be diving this morning to work on a hydrophone array. The outflow from the Fraser plus very large tides give us a very narrow time window in which to complete the dive. This afternoon we will shift to our East Node site for another dive.
This morning we are in Saanich Inlet to recover the Micro Squid platform and replace a damaged oxygen sensor. We will work on the package and then redeploy it shortly before lunch. The Tully will then transit to the Strait of Georgia where we will dive to conduct maintenance on our hydrophone arrays.
We have just completed a successful dive in Tully Canyon. We are now conducting a short sonar survey and will then begin the transit back to Saanich Inlet. This marks the end of the NEPTUNE maintenance operations for Tully Leg #2.
We will be diving at 0730 tomorrow morning in Saanich Inlet to conduct maintenance on the VENUS observatory.
Winds have dropped but the seas are still too high in Barkley Canyon to dive. We are heading to an alternate site in Tully Canyon where conditions look more favourable.
We should be diving at 0830. Our plans are to spend the day at Tully Canyon and depart for Saanich Inlet in the late afternoon.
Tomorrow we will conduct maintenance dives on the VENUS observatory.
Winds have been building steadily overnight and are now blowing from the north at 35 kts. Seas have increased and we have been forced to cancel diving operation for today (see Deck Cam feed). We will complete our CDT casts and continue with sonar surveys.
We will remain at Barkley Canyon in the hope that the weather abates tomorrow morning.
With the successful deployment of the Folger Deep platform, our inshore engineering work is now complete. We are heading offshore to our Barkley Canyon sites to prepare for ROV dives tomorrow morning. On our way to Barkley we will conduct CTD casts and then start a new series of sonar surveys in a location suspected of having gas seeps. Our dives should start at 0730 Tuesday morning, weather permitting.
0730 - Dive at Barkley Hydrates site, sonar tripod positioning and visual survey
1330 - Dive to location of gas seeps detected during sonar survey
We have just successfully recovered the VPS platform. The operation was completed very smoothly by the Tully deck crew. The sun is shining out here, but the seas have been building, so the captain has made the decision that we should not dive this afternoon.
Instead, we are going to do some more deep water CTD rosettes and continue the echosounder survey for bubble plumes from last night. The current plan is still to deploy Folger Deep Monday morning.
We're right on schedule at the time of this update:
Overnight: Echosounder survey (from Tully)
Sunday morning: Dive to recover VPS platform
Here is an update of our operations and plans for Saturday and Sunday:
We are in Barkley Sound, waiting for a crew change to be completed.

The Tully has returned to IOS in Patricia Bay for a science crew exchange and re-mobilization for the second leg of this operations and maintenance expedition. Plans for today include the installation of a new satellite system through Oceaneering. Tomorrow, Leg 2 of the cruise should see us heading out into the Northeast Pacific Ocean to service NEPTUNE observatory sites Barkley Canyon and Folger Passage. Taking the reins from Richard Dewey, we will now be hearing from Expedition Leader Ian Kulin, who is Ocean Networks Canada's Associate Director for Marine Operations.
Tomorrow (May 7), Verena Tunnicliffe will join us to complete a two-year research effort. Planned are video survey dives up into Patricia Bay, and at least two vertical video profiles along the steep cliff walls deeper in the Inlet. And then Leg #1 will come to an end on May 8. Leg #2 of the Tully cruise will be devoted to servicing several off-shore sites of the NEPTUNE observatory.

The ship is now steaming towards Saanich Inlet. Over the next few days we will re-assemble the Saanich Inlet Instrument Platform and the Oregon State University-led Benthic Oxygen Flux experiments. Benthic surveys are required for two camera projects, and during the last dive we will recover a camera for maintenance. All going well, we should be back at the Institute of Ocean Science dock for the exchange by early afternoon, May 8.

Currently preparing for a dedicated dive to investigate and sort out the navigation system.
Yesterday, the Bottom Boundary Layer platform was deployed and connected to the Strait of Georgia Central Node. Today's plans call for deployment of the Seismic Liquefaction In-situ Penetrometer (SLIP) and Delta Hydrophone Array near the Fraser Delta node, followed by possible deployment of the Eastern Hydrophone Array near the Strait of Georgia Eastern Node.

Today we will finish the sonar surveys at 6AM, and steam to our SoG Central Node site for one platform deployment (the Bottom Boundary Layer package) and one platform recovery (the autonomous CTD mooring). During these deck operations, we will assemble the complicated Seismic Liquefaction In-situ Penetrometer (SLIP). It will be deployed during a slack tide in the early afternoon. This leaves most of the day for Tom to re-assess his hydrophone arrays, and deploy them on Sunday.

Tomorrow we pick up two of Tom Dakin's students (Hannan and Kristen) and Gwyn Lintern of NRCan from Steveston, and continue the deployments near the Delta Node. First up will be the Delta Dynamics Laboratory (DDL) at the end of its own kilometre extension cable, up-slope from the Delta Node. This cable is presently being spooled onto the ROV reel. We will now add an extra dive at the end of the day to recover the ONCCEE platform.

The ship slowly streamed into the Strait of Georgia early this morning. After a few days of strong winds, we brought calm to the Strait. But the mighty Fraser is cranking up it's flow, as the Rocky Mountain snow begins to melt. With a 5 fold increase in fresh water volume in May, there is an equal increase in the suspended sediment. The plume had been detected in our Ferry data to have been broadening over the last few weeks, and it clearly now fills a majority of the southern Strait.
The next few days we be at the Delta Laboratory site. After a staff picking up at Steveston early May 2, we will scout out the northern end of the Delta cable, and get the Delta mini-Node re-built, deployed, and connected. The first of two tech-demo hydrophone deployments may finish the day. On May 3, Gwyn Lintern (NRCan) will join us and we will lay a cable and deploy a new DDL platform. May 4 will focus our efforts on the Seismic Liquefaction In-situ Penetrometer (SLIP). This leaves a final hydrophone array and the Bottom Boundary Layer (Dalhousie and MUN) platform for SoG Central.

Today we'll focus on the recently (April 26) laid Delta extension cable. Our first dive will connect the south end to the SoG East Node. Another dive at the north end of the extension cable will be necessary to secure it, and determine where to deploy the new Delta mini-Node. Time permitting, we'll deploy and connect the mini-Node. The Fraser River freshet is starting, so we might encounter strong surface currents, laden with silt and sediments.
First Dive, diving soon:
Dive OE0028 Objectives:
We finished rigging the navigation beacon assembly and got away from the dock reasonably early. A multitasking effort to test the ROV navigation system while conducting the first CTD and Rosette cast, accommodated a first dive before lunch. This went smoothly. The afternoon saw another dive and platform recovery and the deployment of a vital autonomous mooring at the entrance to Saanich Inlet. We deployed the new forensics platform after dinner and then dove to connect it. A quick return to the IOS dock to exchange a dozen platforms, and we're now heading over to the Strait of Georgia.
For details, see the Daily Log, 30 April.
We will either sail at 06:15 or 07:15 tomorrow morning, depending on status of ROV systems. Plans for tomorrow include:
On board today for forensics operations: Dr. Gail Anderson and Chantal Turpin

On 29 April 2013, our Twitter handle for expedition operations changed from @nc_operations to @oceanetworksops.
On April 29, ONC embarks on a series of maintenance cruises to service both the VENUS and NEPTUNE cabled observatories. Over the next two months, we’ll execute three of our eight 2013 expeditions, including two back-to-back cruises on the CCGS John P. Tully (April-May), servicing facilities first in the Salish Sea (VENUS) and then off-shore at Folger Passage and Barkley Canyon (NEPTUNE).
