This dataset has been extracted as part of an exercise to assemble "all" Cefas
Temperature Data and publish it in a Data paper. It is one of 17 Cefas data
sources assembled. ESM2 is a Cefas developed micro logger for applications
requiring a small low power logger with integrated sensors and battery. It has
standard sensors for conductivity, temperature, depth, optical backscatter and
roll & pitch. Data are saved compact flash cards which are easily removed
for rapid data transfer. It was initially developed to be a handheld profiler
that could be used from small boats and/or when a conventional large rosette
couldn't be used. It is now used routinely in place of traditional CTD
equipment e.g. on SmartBuoy related work and, because it also accommodates
optional sensors, it is widely used on RV Cefas Endeavour research cruises,
providing profiles of the water column for plankton and fisheries work. The
temperature sensor used is an FSI CT model.
