WINNIE THE POOH

The upper Tamar estuary was surveyed using the smaller vessel Winnie the Pooh which deployed a multi-parameter meter to measure temperature, salinity and dissolved oxygen at every 1m depth at each station. A Niskin bottle was used to collect and prepare surface water samples for chlorophyll-a and nutrient lab analysis using methods described by Strickland and Parsons (1972) ([10]). A zooplankton sweep net (with diameter 0.5m and mesh size 200µm) was also deployed at three of the stations – one low salinity, one at a medium salinity and one high salinity, with formalin added to fix the live samples.

This was carried out from site 1 through to site 14. See the map below for locations of each station in relation to B33 - the uppermost station surveyed by the Falcon Spirit.
