Moving vessel profiler (MVP) transects from PolarFront 2022-05 cruise

MVP transects 2022-05 The Moving Vessel Profiler (MVP) was deployed to collect data with high-spatial resolution along transects aiming to cross the front. Instruments contained in the profiling unit ("fish") of the winch were a CTD (AML µCTD), a fluorescence sensor (WETLABS) and a laser optical plankton counter (LOPC). Together the instruments yield data on the physical environment, phytoplankton, zooplankton and other particle distributions. Weather conditions during the cruise allowed sampling along two transects (S1 and parts of S2). However, S1 did not cross the polar front due to too thick ice cover in the North. The south (waves to high) and north (ice) of transect S2 were sampled by a different platform, data elsewhere, together resulting in a complete transect crossing the front.
