Changes in the color of sea water caused by algal bloom has continuously risen in recent decades. This increase is due to the harmful effects of human activities that allow sea water to change from a normal to an abnormal state. Satellite sensors are the most accessible, cost-effective means of monitoring. They have been allocated to a large number of marine science studies. The MODIS satellite...
Background and Objectives: Influence of water mass on sound propagation in the Gulf of Aden underwater acoustics used for communication, navigation and identification of objects by both humans and marine mammals and for investigating the detrimental effects of anthropogenic activities (e.g. pile driving, seismic survey and ships) on marine animals. The Gulf of Aden presents a unique ecosystem t...
Despite the importance of the optical properties such as the downwelling diffuse attenuation coefficient for characterizing the upper water column, until recently no in situ optical measurements were published for the Red Sea. Kirby et al. used observations from the Coastal Zone Color Scanner to characterize the spatial and temporal variability of the diffuse attenuation coefficient (Kd(490)) i...
In the recent years, there is evidence of training a red type of zebrafish which differs from wild-type in body color. There is not any document how it reaches to the ornamental fish farms of Iran but at first, it was a doubt it belongs to a morphotype or genetic modification (GM). First of all, a set primer was designed to validate zebrafish species. Mitochondrial 16srDNA was selected and ampl...
The Red Sea holds one of the most diverse marine ecosystems, primarily due to coral reefs. However, knowledge on large-scale phytoplankton dynamics is limited. Analysis of a 10-year high resolution Chlorophyll-a (Chl-a) dataset, along with remotely-sensed sea surface temperature and wind, provided a detailed description of the spatiotemporal seasonal succession of phytoplankton biomass in the R...
*Correspondence: Christian R. Voolstra, Red Sea Research Center, King Abdullah University of Science and Technology, Building 2, Room 2226, 23955-6900 Thuwal, Saudi Arabia e-mail: christian.voolstra@ kaust.edu.sa The Red Sea is the world’s northernmost tropical sea. The 2000 km long, but narrow basin creates distinct environmental conditions along its latitudinal spread. The Red Sea displays a ...
It is usually assumed that metabolic constraints restrict deep-sea corals to cold-water habitats, with 'deep-sea' and 'cold-water' corals often used as synonymous. Here we report on the first measurements of biological characters of deep-sea corals from the central Red Sea, where they occur at temperatures exceeding 20°C in highly oligotrophic and oxygen-limited waters. Low respiration rates, l...
