The Arabian Sea: A Natural Experiment in Phytoplankton Biogeography

نویسنده

  • A. Michelle Wood
چکیده

My long-term goal is to contribute to our understanding of the way different marine ecosystems function, and to the role of natural selection and micro-evolutionary processes in ecosystem resistance and resilience. In particular, I am interested in the interaction between physical, chemical, and bio-optical properties of the water column and the distribution, productivity, and genetic diversity of different phytoplankton taxa. An underlying premise of my research is that the taxonomic composition of the phytoplankton community has a large effect on the dynamics of the ecosystem, and that a taxon-based approach which considers physiological and genetic factors unique to each taxa is needed to understand and predict changes in ecosystem structure and function.

Estimation of Phytoplankton Responses to Hurricane Gonu over the Arabian Sea Based on Ocean Color Data

In this study the authors investigated phytoplankton variations in the Arabian Sea associated with Hurricane Gonu using remote-sensing data of chlorophyll-a (Chl-a), sea surface temperature (SST) and winds. Additional data sets used for the study included the hurricane and Conductivity-Temperature-Depth data. Hurricane Gonu, presenting extremely powerful wind intensity, originated over the cent...

Distribution of diverse nitrogen fixers in the global ocean

[1] We employ a global three‐dimensional model to simulate diverse phytoplanktonic diazotrophs (nitrogen fixers) in the oceans. In the model, the structure of the marine phytoplankton community self‐assembles from a large number of potentially viable physiologies. Amongst them, analogs of Trichodesmium, unicellular diazotrophs and diatom‐diazotroph associations (DDA) are successful and abundant...

Warming of the Eurasian landmass is making the Arabian Sea more productive.

The recent trend of declining winter and spring snow cover over Eurasia is causing a land-ocean thermal gradient that is particularly favorable to stronger southwest (summer) monsoon winds. Since 1997, sea surface winds have been strengthening over the western Arabian Sea. This escalation in the intensity of summer monsoon winds, accompanied by enhanced upwelling and an increase of more than 35...

Distribution and abundance of phytoplankton in Iranian shores of the Caspian Sea and its relationship with reduction of Rutilus frisii and Chelon auratus catch

The aim of this study was to investigate the changes in the structure of the plankton community in the southwestern Caspian Sea and its relationship with the reduction of Rutilus frisii and Chelon auratus catches. The current study was conducted seasonally in the coasts of Guilan provience from 2020 to 2021. A total number of 48 genera and species of phytoplanktons were identified. Tthe finding...

The Northeast Monsoon's impact on mixing, phytoplankton biomass and nutrient cycling in the Arabian Sea

In the northern Arabian Sea, atmospheric conditions during the Northeast (winter) Monsoon lead to deep convective mixing. Due to the proximity of the permanent pycnocline to the sea surface, this mixing does not penetrate below 125 m. However, a strong nitracline is also present and the deep convection results in signi"cant nitrate #ux into the surface waters. This leads to nitrate concentratio...
