Global Climate Change Research Study to determine and understand global scale processes controlling the time-varying fluxes of carbon and associated biogenic elements in the ocean.

POSTDOCTORAL RESEARCH: Biogeochemical Oceanography at BIO - Bedford Institute of Oceanography (Nova Scotia/Canada) 1990 - in collaboration with the University of Kiel (Germany) - Kiel Marine Research Institute.


RESEARCH STUDIES:

•  Participation in interdisciplinary JGOFS (Joint Global Ocean Flux Study) program – associated with the Global Climate Change Research Study to determine and understand global scale processes controlling the time-varying fluxes of carbon and associated biogenic elements in the ocean.

•  Develop a capability to predict on a global scale the response of oceanic biogeochemical processes to anthropogenic perturbations, in particular those related to global climate change.

•  Participation in two-months JGOFS expedition on CSS HUDSON.

•  Examining the role in the transfer of organic material and carbon dioxide from the euphotic zone – with highest biomass production – to the deep sea. Seasonal dynamics of the North Atlantic Ecosystem.

•  Conducting ocean circulation studies and copepod grazing experiments.

•  Physiological and behavioral studies of Atlantic copepods.

•  Multidisciplinary oceanographic research (biochemical and physical oceanography).

•  Physical oceanographic equipment used onboard the CSS HUDSON included:

•  Fluorometer - studying ocean turbidity and chlorophyll profile and associated plankton organism distribution, BIONESS - multiple plankton sampler equipped with oceanographic equipment to study distribution of temperature and salinity and density of plankton, Batfish - for temperature and salinity profile, Secchi Disk – for determining turbidity and light penetration, DO meter – to study dissolved oxygen, pH meter – to determine pH levels.

•  Sediment traps to collect organic matter at various depths and determine biomass.

•  Biochemical instruments used onboard the research vessel to analyze carbon dioxide and ammonia production and oxygen consumption of Atlantic copepods.
