High export via small particles before the onset of the North Atlantic spring bloom
Sinking organic matter in the North Atlantic Ocean transfers 1–3 Gt carbon yr from the surface ocean to the interior. The majority of this exported material is thought to be in form of large, rapidly sinking particles that aggregate during or after the spring phytoplankton bloom. However, recent work has suggested that intermittent water column stratification resulting in the termination of dee...
متن کاملBiophysical forcing of particle production and distribution during a spring bloom in the North Atlantic
-As part of the North Atlantic Bloom Experiment (NABE), CTD/transmissometer profiles were made on two cruises at 47°N, 20°W in spring 1989 to quantify the increase in particles during a phytoplankton bloom in relationship to biophysical forcing factors. Water samples were filtered to obtain particle mass concentrations for calibration of beam attenuation (beam c) from the transmissometer. Shipb...
متن کاملA seasonal diary of phytoplankton in the North Atlantic
*Correspondence: Christian Lindemann, National Institute of Aquatic Resources, Technical University of Denmark, Jægersborg Alle 1, 2920 Charlottenlund, Denmark e-mail: [email protected] In recent years new biological and physical controls have been suggested to drive phytoplankton bloom dynamics in the North Atlantic. A better understanding of the mechanisms driving primary production has poten...
متن کاملSimulation of Observed PCBs and Pesticides in the Water Column during the North Atlantic Bloom Experiment.
The dynamics of persistent organic pollutants in the oceans are not well constrained, in particular during a bloom formation and collapse. Polychlorinated biphenyls (PCBs) and some pesticides were measured in air, water, and zooplankton tracking the North Atlantic Bloom in May 2008. Lower weight PCBs were entering the water column from the atmosphere during the main bloom period but reached equ...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
