Febuary 15 | Febuary 16 | Febuary 17 Febuary 7 Since we have over 12 moorings to throw in the water and we can't load them all on the ship at once, we have to schedule 2 legs. Everything for the first leg is loaded and ready to go. Unfortunately, we have to wait one more day to leave WHOI because of a problem with our Vertical Linear Array (VLA) of hydrophones. Trouble always waits until the most inopportune time to raise its ugly head. Fortunately, we caught the problem before leaving the dock. Conditions Temp: 35° F Wind dir: SW Wind spd: 5 knt Weather: nice Febuary 8 Guess what? High winds and large swells from a storm will keep us in port for one more day as it goes "harmlessly out to sea!" ETD tomorrow, Sunday, Feb 9 at noon. Conditions Temp: Chilly Wind dir: Wind spd: Weather: Febuary 9 The weather is finally cooperating. After a little shoveling, we left the dock at noon and are on our way. We should be on station at dawn tomorrow. ETD tomorrow, Sunday, Feb 9 at noon. Conditions Temp: 35° F Wind dir: NE Wind spd: 10 knt Weather: Nice February 10 Work day 4:00 AM to midnight. We deployed three 200 hz sources, one 400 hz source, and two guard buoys. That's a little over 20 tons of equipment. Temperature profiles from last night's CTD casts show that there are great differences in the upper mixed layer depths near a front at our site. The mixed layer depth is greater than 100 meters just seaward of the front and at the front the mixed layer is quite shallow, less than 15 meters. Conditions Temp: 30-34° F Wind dir: SW Wind spd: 5-15 knt Weather: Not Bad Feb 11 The acoustics portion of the experiment officially started today. We deployed the 'Shark of Science' hydrophone array, some more guard buoys (one twice!), and steamed off the shelf break to pick up some damaged equipment that was deployed earlier by another scientist at WHOI. Last night a longer section of CTD casts was performed along the Eastern edge of our experiment area. The shelfbreak front is relatively narrow (~20km) here with a temperature contrast across the front of 4 degrees C. The front is shoreward of its normal position presumably due to a presense of a warm core ring, or remnant of ring structures, over the upper slope. We checked satellite images for sea surface
temperature in our study area. The seasoar has already gathered some temperatures from the western section of our experimental area. Last updated: June 23, 2011 | |||
