The present paper discuss on spatial and temporal distribution of chlorophyll-a (Chl-a) in the coastal and offshore waters of northeastern Arabian Sea, using Advanced Earth Observation Satellite OCTS data. The Chla concentration found high all along the western Indian coastal waters, with significant variations at Gulf of Cambay and Gulf of Kutch regions, ranging from 0.05 to 4.0 mg m. Several ...

Background: Sulfur dioxide is one of the important pollutants that at the present time cause irreparable damage to environment and human health. The aim of present study was to study and comparison the effects of SO2 on respiratory and cardiovascular deaths in Bushehr city. Materials and Methods: This analytical study was conducted in Bushehr city during 2011. In the first stage data were colle...

This paper investigates the performance of MERIS reduced resolution data to monitor water quality parameters in the Berau estuary waters, Indonesia. Total Suspended Matter (TSM) and Chlorophyll-a (Chl-a) concentration were derived from MERIS data using three different algorithms for coastal waters: standard global processor (MERIS L2), C2R and FUB. The outcomes were compared to in situ measurem...

this study was carried out to investigate the occurrence of potentially pathogenic species of vibrio in sea water and estuarine environments of the caspian sea in the golestan province of iran. a total of 127 water samples from coastal waters as well as from river and estuaries were collected and analyzed by culture, during april and september 2001. following prompt centrifugation, the resuspen...

In this lesson, students will learn methods for spawning bivalve mollusks (e.g. clams or oysters) using thermal induction. Students will acquire skills in using an ocular micrometer to measure the diameter of bivalve eggs and the length of bivalve larvae. The following lesson plan will have students monitoring the density of larvae in their culture system and understanding production protocols ...

Coastal salt marshes are a buffer between the uplands and adjacent coastal waters in New England (USA). With increasing N loads from developed watersheds, salt marshes could play an important role in the water quality maintenance of coastal waters. In this study we examined seasonal relationships between denitrification enzyme activity (DEA) in salt marshes of Narragansett Bay, Rhode Island, an...

China is facing intense coastal eutrophication. Large-scale seaweed aquaculture in China is popular, now accounting for over 2/3's of global production. Here, we estimate the nutrient removal capability of large-scale Chinese seaweed farms to determine its significance in mitigating eutrophication. We combined estimates of yield and nutrient concentration of Chinese seaweed aquaculture to quant...

survey on zooplankton composition was studied during june 2015 to march 2016, by selecting six stations along the coastal waters of bushehr (the northwest persian gulf). twenty four zooplankton taxa were identified, and the different zooplankton groups represented twenty-one families. copepoda was recorded with the most abundance (53.30 %) followed by malacostraca (32.87 %), which in turn was f...

The Hyperion instrument on-board the EO1 satellite is an imaging spectrometer capable of acquiring hyperspectral data with over 200 contiguous spectral bands of about 10 nm bandwidth. The instrument is not designed for ocean observation. Nevertheless, case 2 water near the coastal regions with high sediment loading usually has higher reflectance in the visible wavelength region than the clear c...

Tidal forcing and its fortnightly variation are known to be one of the main regulating agents of physical and biogeochemical signatures in the Strait of Gibraltar and surrounding areas. Samples obtained during spring and neap tides in the region were analyzed to determine the influence of this tidal variation on the submesoscale distribution of water masses and biological elements. During sprin...
