+--------------------------------------------------------------------------+ | KNORR CRUISE SYNOPSIS | +--------------------------------------------------------------------------+ Voyage - Leg: KN 195-07 Voyage Dates: 27 April to 1 May 2009 Chief Scientist(s): Eric Grabowski (Karl) Address: Phone: Email: Cruise Objective: The objective of a HOT cruise is to maintain a collection of hydrographic and biogeochemical data at the Hawaii Ocean Time-series (HOT) stations. Four stations are to be occupied during the cruise, in the following order: Science Activities: 1) Station 1, referred to as Station Kahe, is located at 21* 20.6'N, 158* 16.4'W and will be occupied on the first day of the cruise for about 2 hours. 2) Station 2, referred to as Station ALOHA is defined as a circle with a 6 nautical mile radius centered at 22* 45'N, 158*W. This is the main HOT station and will be occupied during the 2nd, 3rd, and 4th days of the cruise. 3) Station 50, is the site of the WHOTS Mooring, located at 22* 46'N, 157* 53.83'W will be occupied on the 4th day of the cruise for about one hour. 4) Station 6, referred to as Station Kaena, is located off Kaena Point at 21* 50.8'N, 158* 21.8'W will be occupied on the 4th day of the cruise for about 2 hours. Upon arrival to Station Kahe a 1,300 lb. weight-test cast to 500 m, one CTD cast to 1000 m, and a PRR cast will be conducted at this location. The single CTD cast is to be conducted for collection of continuous profiles of various physical and chemical parameters. Water samples are to be collected at discrete depths for biogeochemical measurements. After these operations are satisfactorily completed, the ship will proceed to Station ALOHA. Upon arrival at Station ALOHA, a free-drifting sediment trap array is to be deployed. The sediment trap array will stay in the water for about 52 hours. This will be followed by one shallow CTD cast to 200 m and one 1000 m CTD cast to collect water for the primary productivity array. After this, the free-drifting primary productivity array will be deployed for 12 hours. A full-depth CTD cast will then be conducted after the deployment of the primary prodcution array, followed by 1000-m CTD casts at strict 3 hour intervals for at least 36 hours for continuous and discrete data collection, ending with another full-depth CTD cast. Another free-drifting array (gas array) will be deployed during the cruise for 24 hours for incubation experiments. A plankton net will be towed near noon and midnight for 30-min intervals. There will be 8 tows scheduled but only six need to be completed. Will use the capstan. A Profiling Reflectance Radiometer (PRR) will be deployed twice at ALOHA for half-hour periods near noon time. A package including a Wet Labs AC9, a Chelsea Fast Repetition Rate Fluorometer (FRRf), and a SeaBird Seacat will to be used to profile the upper 200 m at Station ALOHA around noon time twice and in the early morning once. Will use the capstan. After CTD work at Station ALOHA is accomplished, the ship will transit to recover the floating sediment trap array and the gas array on the last day of work at ALOHA. After recovering the arrays, the ship will then transit to Station 50 to conduct a one-hour 200-m CTD yo-yo cast. Following the yo-yo CTD cast, light casts (PRR and AC9/FRRf) will be completed at Station ALOHA. After operations at Station ALOHA are complete, the ship will transit to Station Kaena. A near-bottom CTD cast (~2500 m) is to be conducted at Station 6 including salinity and chlorophyll samples for calibration, after which the ship will transit to Snug Harbor. The following instruments are to collect data throughout the cruise: shipboard ADCP, thermosalinograph, underway fluorometer, anemometers, and the pCO2 system.
