August 14, 2022 16:10 local (Pacific): ROPOS is back aboard and the ship is moving back to Eastern Caldera for dive R2215, a CTD recovery and redeployment. The vehicle will enter the water with the tool basket latched below containing the CTD tripod and cable for a roughly 5-hour dive to connect the new instrument and recover the current one.

August 14, 2022 11:45 local (Pacific): Dive R2213 is complete and the Thompson is moving into position for Dive R2214, which will head for the Anemone hydrothermal chimney in the ASHES vent field to do some additional water sampling for Dr. Anderson’s microbial work.

August 14, 2022 09:10 local (Pacific): Dive R2213, a sampling dive with Dr. Rika Anderson’s group using the Universal Fluid Obtainer (UFO) installed on the ROPOS porch to sample fluids and particles for microbial analysis, began at 0259 this morning.  Sampling is complete and ROPOS is on its way to the surface with the samples.  

August 14, 2022 01:03 local (Pacific):  With R2212 back on deck after the turn of the CTD tripod and retrieval of the A0A we are now headed back towards the Eastern Caldera for a sampling dive with Dr. Rika Anderson’s group using the Universal Fluid Obtainer (UFO) installed on the ROPOS porch to sample fluids and particles for microbial analysis.

August 13, 2022 16:27 local (Pacific): ROPOS is back on board after a successful dive to turn the Vent Fluid and DNA Sampler instruments (RASFL/PPSDN) and collect fluid samples for a microbial DNA PI project. The Thompson is now en route to the Central Caldera site, where dive R2212 will be launched to swap out a CTD tripod, deploy an Acoustic Array cable for a PI project, and recover a different PI instrument, Dr. William Wilcock’s A0A calibrated pressure sensor (which self-calibrates to remove drift).

August 13, 2022 8:25 local (Pacific): Dive R2210, replacement of the TRHPH sensor was successful.  The temperature probe was placed into a vent that was producing fluids at around 300° C.  ROPOS returned to the surface at 0051 local.  The next dive, R2211, began  at 0506 and is still underway at this time.  Diffuse Fluid samples are being collected from several Hydrothermal Vents in the Caldera.  

August 12, 2022 16:42 local (Pacific): The Thompson has arrived at Axial Caldera, and ROPOS is descending towards the International District vent field (~1500 meters deep) with the replacement Hydrothermal Vent Fluid Temperature and Resistivity sensor (TRHPH). They will survey the site and swap out the sensor before returning to the surface to prepare for the next dive.

August 12, 2022 14:36 local (Pacific): The verification CTD cast was successfully concluded, and the Thompson is now headed for the International District vent field in the caldera of Axial Seamount. The next dive (R2210) will be to replace the Hydrothermal Vent Fluid Temperature and Resistivity sensor, which measures the chemistry of the mineral-rich fluid plumes that emanate from cracks on the seafloor.

August 12, 2022 08:30 local (Pacific): We arrived at Axial Base at 0200 this morning and quickly got to work on the Axial Base Shallow Profiler with 2 dives in rapid succession (R2207 and R2208).  We will be launching ROPOS within the hour for the last dive here (R2209) to complete the turn of the shallow profiler instrumentation, followed by a verification CTD cast, before moving on to the Axial caldera. 

August 11, 2022 08:22 local (Pacific): We have successfully completed the turn of the Endurance Oregon Offshore Shallow Profiler infrastructure. We’re one hour into our 18 hour transit out to Axial Base, with an estimated arrival of 01:30 on August 12. Once we arrive, we’ll swap out the Axial Base Shallow Profiler infrastructure before starting work on the seafloor sensors.

August 10, 2022 21:53 local (Pacific): Dive R2204 was completed at 18:41 this evening. Dive R2205 began at 20:51 with ROPOS attached to the replacement Platform Interface Assembly. In addition to installing the replacement platform, ROPOS will recover the Science Pod installed in 2021 and will replace it with a new one on the next dive.

August 10, 2022 13:51 local (Pacific): Dive R2204 is underway, to recover the Oregon Offshore Shallow Profiler 200m platform instrument frame (PC01B). This is the first of a series of dives at this site, which will swap out all profiler and platform instruments.

August 10, 2022 13:36 local (Pacific): ROPOS is currently conducting a test latch into the Oregon Offshore platform assembly in preparation for Dive R2204, which will be the recovery of the Shallow Profiler 200m platform instrument frame.

August 10, 2022 08:05 local (Pacific): Transit to Oregon Offshore site is just about complete. ROPOS will begin preparations to swap out the vertical mooring shallow profiler science pod and platform.

August 10, 2022 04:50 local (Pacific): Extension cable has been successfully installed and power has been restored to Southern Hydrate Ridge!  After PN1B is secure ROPOS will ascend and we will begin our ~1hr transit to Oregon Offshore to start work on swapping out the vertical mooring shallow profiler science pod and platform.

August 9, 2022 21:21 local (Pacific): We are  currently descending on dive R2203 in order to complete the installation of PN1B Extension Cable 

August 9, 2022 18:15 local (Pacific): ROPOS is back on deck and we are starting deck operations to spool the 500 meter extension cable that will connect the Primary Node to Southern Hydrate Ridge.

August 9, 2022 17:10 local (Pacific): ROPOS has left bottom- the next dive (Dive R2203) will be to install the extension cable.

August 9, 2022 16:12 local (Pacific): DIVE R2202 – ROPOS removed the recovery bridle from PN1B and is placing a navigaton beacon on the seafloor.

August 9, 2022 12:19 local (Pacific): ROPOS is in the water (dive R2202) and descending towards the PN1B primary node to deploy a beacon as part of the work to connect the extension cable to Southern Hydrate Ridge. 

August 9, 2022 10:13 local (Pacific): The Thompson is at the Primary Node PN1B site and the ROPOS vehicle is being prepped to begin extension cable installation operations. 

August 9, 2022 05:38 local (Pacific): ROPOS has completed dive R2201 with the successful turn of the Slope Base CTD tripod. We have started our transit to the PN1B site to begin operations to install an extension cable to connect the primary node to Southern Hydrate Ridge.

August 8, 2022 18:47 local (Pacific): ROPOS has entered the water on dive R2201! The vehicle is descending to the seafloor at Slope Base (~2900 m) and will be swapping out a three-instrument tripod (CTD, oxygen, and an AC-S spectrophotometer) using a tool sled latched below the vehicle. Total dive time should be about six hours.

August 8, 2022 16:01 local (Pacific): The Thompson is on site at the Slope Base seafloor node (LJ01A) and ROPOS is prepping for the first dive (R2201). The vehicle will descend to the seafloor at ~ 2900 m and swap out the existing tripod with three instruments (CTD, oxygen, and an AC-S spectrophotometer) for a new one.

August 8, 2022 10:15 local (Pacific): The Thompson has left the dock, and is heading to the Slope Base site where the first ROV dive of the 2022 RCA cruise will be to swap out a tripod assembly of instruments on the seafloor. ETA ~15:15 local time.

August 7, 2022 12:52 local (Pacific): Crane operations continue, students have begun to arrive at the ship, and mobilization of Leg 1 is on track for a departure on August 8th.

August 6, 2022 16:45 local (Pacific): ROPOS mobilization continued this morning with the loading of the LARS and the majority of the RCA equipment and supplies for the cruise as well as the instruments and infrastructure to be turned during Leg 1. After lunch, mobilization of ROPOS continued and the ROV was onboard by 1430. The ROPOS Team also successfully completed a 19,000 lb water bag test of the LARS system. 

August 5, 2022 08:00 local (Pacific): Mobilization for the 2022 RCA O&M Cruise (TN407) aboard the R/V Thompson commenced at the NOAA MOC-P pier in Newport, OR. The first day concentrated on using the shore crane to load the ROPOS ROV equipment and installing the infrastructure necessary to mobilize both the heave-compensating LARS Crane as well as the ROV itself onto the ship. The last time ROPOS was loaded on the Thompson was back during the 2015-2016 RCA O&M Cruise, and it was exciting to see it happen again!

July 15, 2022 16:02 local (Pacific): The RCA team is busy finishing up final testing, inventories and packing in preparation to begin our mobilization on August 5th onboard the R/V Thompson.
