Abstract EN
An oceanic eddy of size about 150 kilometer diameter observed in the northeastern Arabian Sea using remote sensing satellite sensors; IRS-P4 OCM, NOAA-AVHRR and NASA Quickscat Scatterometer data.
The eddy was detected in the 2nd week of February in Indian Remote Sensing satellite (IRS-P4) Ocean Color Monitor (OCM) sensor retrieved chlorophyll image on 10th February 2002, between latitude 16°90′–18°50′N and longitude 66°05′–67°60′E.
The chlorophyll concentration was higher in the central part of eddy (~1.5 mg/m3) than the peripheral water (~0.8 mg/m3).
The eddy lasted till 10th March 2002.
NOAA-AVHRR sea surface temperature (SST) images generated during 15th February-15th March 2002.
The SST in the eddy’s center (~23°C) was lesser than the surrounding water (~24.5°C).
The eddy was of cold core type with the warmer water in periphery.
Quickscat Scatterometer retrieved wind speed was 8–10 m/sec.
The eddy movement observed southeast to southwest direction and might helped in churning.
The eddy seemed evident due to convective processes in water column.
The processes like detrainment and entrainment play role in bringing up the cooler water and the bottom nutrient to surface and hence the algal blooming.
This type of cold core/anti-cyclonic eddy is likely to occur during late winter/spring as a result of the prevailing climatic conditions.
