Chlorophyll concentration

Chlorophyll  a concentration is an index of phytoplankton biomass and it is the most common property that characterizes marine productivity. Satellite remote-sensing images of ocean colour, calibrated as chlorophyll concentration provide a unique approach to monitor  the productivity of the oceans and seas worldwide. Read More...

Omani coast

The coast of Oman
 
The Sultanate of Oman occupies the south-eastern corner of the Arabian Peninsula and has a total area of 312,500 km2.
It is bordered in the north-west by the United Arab Emirates, in the west by Saudi Arabia and in the south-west by Yemen. A detached area of Oman, separated from the rest of the country by the United Arab Emirates, lies at the tip of the Musandam Peninsula, on the southern shore of the Strait of Hormuz.

Coastal and Shelf Ecosystems of Oman

Our research is aimed at advanced understanding of mesoscale, seasonal and climate driven variability of coastal and shelf ecosystems of Oman. Basic approach involves 4 parallel lines of activity: retrospective data analysis, field sampling, remote sensing, and modeling. In retrospective analysis, the data from onboard measurements we assembled, have incorporated over 90 expeditions carried out by USA, UK, Germany, Japan and other countries in the western Arabian Sea, from 1950 to 2012:

Western Atabian sea map

The basic physical and chemical characteristics selected for the analysis were represented by wind speed, atmospheric temperature, sea temperature(Figure 2), salinity, dissolved oxygen concentration, water acidity (pH), the concentration of nutrients, chlorophyll-a, phytoplankton, mesozooplankton, and landings of small and large pelagic fish species:

Decadal profiles

Our coastal time series (along with remote sensing and modeling) have enabled us the seasonal and mesoscale variability to be studied. Coastal currents, along with the currents of the Arabian Sea interior generates a dense field of mesoscale eddies.We found that spatial-temporal characteristics of these eddies are valuable tools in understanding seasonal and interannual fluctuations of sardine landings (contributing ~ 50% to the fishery in the region).

dynamical topography and distribution of chlorophyll-a concentration

An example of dynamical topography and distribution of chlorophyll-a concentration.

In extending shelf research, we have launched sea gliders. Along with coastal time series, modeling and remote sensing, gliders allow us to monitor the development of algal blooms and shelf hypoxia in the region.
