Cascadia Initiative on the RV Oceanus – 2013

April 9th, 2014 · No Comments · 2013 - R/V Oceanus, Recovery, SIO, video

Poor Internet connections prevented Bill from live-blogging the 2013 cruise, though he was able to capture some video (below) that provides an idea of what working conditions can be like at sea. You can learn about the season’s objectives and accomplishments on the Cascadia Initiative 2013 Cruise page. Videos from the 2013 cruise: Bird’s eye […]

Deepest Recovery

July 16th, 2012 · No Comments · 2012 - R/V New Horizon, Instrumentation, Missions, Procedures, Recovery, Seismometers, SIO

Monday, July 16, 2012 The weather today cooperated with the successful recovery of three of our deepest deployed Abalone seismometers. The seas were calm, with 3 to 6 foot swells. The wind was out of the north, picking up to 11 knots as evening approached. The depth of the seismometers’ deployment directly effects their recovery […]

Friday the 13th – First night at sea

July 13th, 2012 · No Comments · 2012 - R/V New Horizon, Missions, Procedures, Recovery, Seismometers, SIO

Aboard the New Horizon Departed the NOAA’s MOC-P dock at approximately 16oo hours. The weather was clear with ocean swells coming in from the Northwest. The fifteen instruments to be recovered were some of those that were deployed from the October voyage of the Wecoma. These are the Scripps Institute of Oceanography “Abalones”.  Abalones are […]

Dr. Robert Dziak contributed this cruise summary: “The OBS deployment cruise was an unqualified success. Our highly efficient team of sea going professionals was able to maintain a brisk deployment schedule and completed all 25 ocean bottom seismometer deployments within 8 days. We averaged 3 deployments a day, including time for instrument surveys to derive […]

A Beautiful Monday at Sea

October 18th, 2011 · No Comments · 2011 - R/V Wecoma, Deployment, LDEO, Seismometers, SIO

We have traveled north to test two Cascadia seismometers that were deployed earlier during the first leg during July. A specific frequency of sound (between 9 and 13 kilohertz) is sent down to check if the instrument package is working. Sometimes a fishing trawl can flip over the seismometer, rending it useless. If the instrument […]

Second Day at Sea

October 16th, 2011 · No Comments · 2011 - R/V Wecoma, 2011 Crew, Deployment, LDEO, SIO

Yesterday, we deployed three seismometers, two “Abalones” from Scripps Institute of Oceanography with the trawl resistant design and one from the Lamont-Doherty Earth Observatory (LDEO) called “Cascadian” which also has an absolute pressure gauge and hydrophone. These seismometers are generally deployed deeper along the continental margin.
