Última Phytoplankton composition in coastal lagoons of different trophic status in Northern Colombia determined by microscope and HPLC-Pigment analysis OceanDocs Gocke, K.; Meyerhöfer, M.; Mancera P., J.E.; Vidal, L.A.. The regional differences in the composition of the phytoplankton assemblages in several coastal lagoons of the “Outer Delta of the Río Magdalena” (Caribbean coast of Colombia) were determined using microscopic counting and HPLC-pigment measurements. The study sites can be classified as 1) a group of limnic lagoons with relatively low (5.5-19 µg/l) chlorophyll a (chl a) concentrations and high inorganic suspension loading, 2) a group of brackish lagoons with high (62-90 µg/l) chl a concentrations and high amounts of organic seston, (two further lagoons form a transition between group 1 and 2, and 3) a fully marine Caribbean bay with very low (0.3 µg/l) chl a and seston concentrations. The regional variations in salinity of the lagoons are due to inflow of...

Ano: 2003 URL: http://hdl.handle.net/1834/3200 Planktonic primary production and community respiration ini several coastal lagoons of the outer Delta of the Rio Magdalena, Colombia OceanDocs Gocke, K.; Mancera P., J.E.; Vidal, L.A.; Fonseca, D.. To understand the responses of the plankton community to the negative large-scale human impacts in a tropical coastal lagoon complex, we carried out a regional survey on primary productivity (PP), community respiration (CR), and contribution of different size fractions of the phytoplankton to overall PP. This comparative study was undertaken in several coastal lagoons within the Outer Delta of the Río Magdalena (Colombia) during the dry season(February/March). PP was measured using the 14C-method with in situ-incubations and CR was determined as oxygen demand, using the Winkler technique. According to their salinities the lagoons were separated into a brackish water group (salinity range 5.9 – 21.8) and a freshwater group, the latter being influenced...
