Objective

The Gyrafor-A-2008 cruise's objective was to determine the vertical distribution of carbonated microplankton along a transect between the SW Pacific oligotrophic gyre and the Equatorial Pacific. It aimed to identify both vertical distribution of cryptic and morphological foraminifera species which are the most widely used markers in paleoceanography, but whose ecology is poorly known. During the cruise, we sampled along a South-North transect along the 162°30'E meridian from 26°S to the equator. At each station, we performed a T, S, chlorophyll profile over the 400 metres on a depth ranging from 0 to 400 metres and took samples of carbonated microplankton (plankton foraminifera) by stratified net hauls (MultiNet, 100 µm mesh) which were either vertical or oblique, depending on the sea conditions. At each station, at least 9 depth intervals were sampled. The plankton net hauls were doubled at some stations in order to isolate plankton foraminifera cells under the stereo microscope on board and preserve them in a buffer for later genetic analysis. We also performed hydrographic T, S, dissolved oxygen profiles at the same stations (from 0 to 500 m), and took seawater samples at different depths corresponding to the plankton net samples. The seawater samples will be used to determine the seawater's d18O and the CID's d13C as well as characterizing the plankton nanoflora. Lastly, we took WP2 net hauls (63 µm mesh) at all stations in order to determine the diversity of the radiolaria zooplankton group. Surface salinity and temperature data were continously recorded by the TSG and hydrographic data complemented by the ADCP. This falls under the ANR young research scientists project PALEO-CTD.
