Passive surface drifter data in the bay of Sept-Îles in 2003 ...

Lagrangian drift data were gathered by Denis Lefaivre in the Bay of Sept-Îles in 2003 as part of work for the Department of Fisheries and Oceans, Canada (DFO).

Description
Summary:Lagrangian drift data were gathered by Denis Lefaivre in the Bay of Sept-Îles in 2003 as part of work for the Department of Fisheries and Oceans, Canada (DFO). The drifters were deployed from the small DFO boat Barachois, and consisted of 2 m long by 10.16 cm wide PVC tubes. These were weighted on one end and affixed with a 22.86 cm ring 20 cm from the other, to increase stability. Positions were recorded every 2 minutes by a GPS emitter inside the top 20 cm of the tube, which remained above water. Sampling was done from September 9 to 11, 2003. ... : Description-----------These drifts were gathered by Denis Lefaivre in 2003, as part of work for the Department of Fisheries and Oceans, Canada (DFO). The longitude, latitudes and time were automatically recorded and were processed to obtain the following parameters: * longitude (degrees east) * latitude (degrees north) * datenum UTC (days since January 0, 0000) * velocity east (meters / second) * velocity north (meters / second) * velocity magnitude (meters / second) * velocity direction (compass degrees) * time after high tide (hours) * water depth (meters) * time UTCSee the referred publication for information on data sets used to obtain these values.These drifters were built from a 2 meter long PVC tube with the GPS beacon on one end, and weight at the other. The PVC tube was 4 inches in diameter. It was weighted such that 20 cm of the tube extended out of the water. A ring 9 inches indiameter was fixed 20 cm from the beacon end of the tube. These drifters were estimated to be affected by currents in the ...
