Cycle 5 and 6 samplings were conducted from west to east following drifter flows.SST is merged from MODIS Aqua and Terra satellites from the period of 22–25 October 2008. Map of A-Front station locations and satellite measured sea surface temperature (SST).Contributions of chemotaxonomically defined taxa to total chlorophyll )] were calculated as described previously (Goericke and Montoya, 1998; Goericke, 2002).We enumerated pico-phytoplankton and heterotrophic bacteria from 2-m L samples preserved with 0.5% paraformaldehyde (final concentration) and flash frozen in liquid nitrogen.We build massive mobile games that break down linguistic and geographic barriers by uniting an unprecedented number of global players in one gaming world.We empower our game developers to push the boundaries of innovation in a player-driven ecosystem.Spatial variability of plankton biomass, community composition and size structure was investigated across a strong frontal transition (A-Front) in the southern California Current Ecosystem in October 2008.Depth profiles were taken across a 25-km transect of nine stations sampled semi-synoptically during one night and for 3 days following drifter arrays in the adjacent water masses.

Sampling began in warm oligotrophic water to the south of the front (32.67°N, 120.56°W) at ∼2100 local time and ended in cool eutrophic water to the north (32.90°N, 120.71°W) at ∼0600 (Fig. The chlorophyll fluorescence profile was observed on the downcast, and bottles were tripped “on-the-fly” on the upcast at variable depths that captured the mixed layer, the peak concentration of the subsurface chlorophyll maximum, if present, and the shoulders and breaks that defined those features.SST is merged from MODIS Aqua and Terra satellites from the period of 22–25 October 2008. Concentrations of lipophilic pigments, chlorophylls and carotenoids, were determined using HPLC.For HPLC analysis, 2.2- or 4.4-L samples of seawater were filtered onto Whatman GF/F filters, stored in liquid nitrogen and extracted in acetone as described by Goericke (Goericke, 2002).The Niskin bottles were sampled for analyses of total chlorophyll ), phytoplankton accessory pigments by high performance liquid chromatography (HPLC), prokaryotic abundance and biomass by FCM and protistan community abundance and biomass by digital epifluorescence microscopy.In addition, we conducted similar sampling during experimental drifter studies in water masses to the north (Cycle 5; 22–24 October) and south (Cycle 6; 26–28 October) of the front (Fig. For each of these experiments (described in Landry, Ohman Map of A-Front station locations and satellite measured sea surface temperature (SST).
