Previous studies reveal that strong cooling is observed along the cyclone track [1-3]. It also plays an important role in enhancing phytoplankton bloom and primary productivity in oligotrophic oceanic waters, especially in cyclone-dominated seas. The Bay of Bengal is the most vulnerable region to hazard of intense tropical cyclones during pre-monsoon (April-May) and post monsoon (October – December) seasons [4]. In recent years the bay experience more than 5 cyclones during the post monsoon season compared with the Arabian Sea. Tropical cyclones depend on the ocean for their energy supply. Observations have shown that the state of the ocean has a great influence on the intensities, structures, and even paths of tropical cyclones [5-9]. Upper ocean is greatly influenced by the cyclone gale winds. The wind stress and pressure drop associated with tropical cyclone generate turbulent mixing in the ocean, generate ocean currents, and alters the ocean’s thermal structure. Strong wind momentum helps to bring the subsurface water from a depth of 60 m, because of that the surface water shows strong cooling (1-7°C) also the very deep mixed layer during post cyclone stage [1013]. This cooling is mainly due to the vertical turbulent mixing induced by the strong momentum flux into ocean currents and accompanied entrainment of cooler thermocline water into the upper mixed layer. The magnitude of the surface cooling plays a vital role on reduction of the energy supply to cyclone for further intensification [13]. The main purpose of the study is to examine the physical and biological changes in the upper layers of the Bay water at different stages of Jal cyclone.","PeriodicalId":308766,"journal":{"name":"Oceanography & Fisheries Open access Journal","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131873600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As fifty percent of the world population lives within 100 km of the coast, human activities have put tremendous pressure on the coastal environment. For instance, excess nutrients that are generated by agriculture and present in domestic waste have been discharged into the oceans by rivers, making many coastal regions hypoxic or even anoxic. Most people do not realize that a substantial fraction of the freshwater on land enters the oceans directly from the seabed, unseen by human eyes. This process is called submarine groundwater discharge (SGD) [15]. Burnett and coworkers [6] were among the first to provide a ballpark estimate that the amount of SGD is 0.2-10% of global river discharge. Since groundwater has been frequently in contact with soil and bedrock for hundreds of years, if not longer, some of the dissolved organic carbon (DOC) in the groundwater as well as particulate organic carbon and CaCO3 in the soil and bedrock are expected to have decomposed or dissolved.","PeriodicalId":308766,"journal":{"name":"Oceanography & Fisheries Open access Journal","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126361923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The general principle of sustainable development adopted by the World Commission of Environment and Development – that current generations should “meet their needs without compromising the ability of future generations to meet their own needs”has become widely accepted. The protection of the environment is an essential part of development. Without adequate environmental protection, development is undermined; without development, resources will be inadequate for needed investments, and environmental protection will fail [1]. The petroleum exploration, production and the associated industry have the potential to impact the environment [2]. Therefore, comprehensive environmental protection plans, including waste management and contingency plans, are needed to optimize the use of offshore oil resources as a tool for achieving sustainable development [3].","PeriodicalId":308766,"journal":{"name":"Oceanography & Fisheries Open access Journal","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132711094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensitivity of Ostracoda on feeble environmental fluctuations, make them a good marker for the interpretation of geological past. Distribution of Ostracod species varies with environmental conditions and sedimentological parameters. They can tolerate a wide salinity ranges [2] and hence, can occur in different environmental settingsmarine, brackish, fresh waters, mangrove ecosystems and wet paddy fields. Ostracoda genera, Krithe is benthic pandemic fauna and is globally distributed [3] which diversely occur in deep sea, escalated greatly by its paleo environmental and paleo-oceanographic applications. Being a temperature dependent, salinity tolerant, mud loving genus and moreover a widely distributed genus across the oceans, the genus and its capacity stands unique for correlation of diverse ocean settings. The occurrence of Krithe is attributed to zone of upwelling and cold-water regions [4]. Different studies pertaining to the deep sea, multi proxy analysis in genera Krithe is handy. The exploration on paleoceanography using the genera is not receiving any mileage, because of lack of a proper compilation.","PeriodicalId":308766,"journal":{"name":"Oceanography & Fisheries Open access Journal","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125182688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concept goes far back in time and was then known as steric changes in sea level caused by change in temperature or salinity [1]. The Holocene sea level oscillations on a centennial bases were sometimes proposed to be driven primarily by steric sea level changes [2]. Mörner showed [3] that the sea level changes were dominated by glacial eustasy up to about 6000-5000 BP (regardless of tectonic differentiation) and thereafter was dominated by the redistribution of water masses. When satellite altimetry commenced in 1992, the lateral redistribution of water masses over the oceans was well monitored [4], whether caused by lateral dislocation of water masses or by differential thermal expansion (or rather a combination of both). Thermal expansion became a part of the concept of global warming [5], claiming that the general warming from 1970 to 2000 also generated a global sea level rise component due to thermal expansion. Often it is used without basic anchoring in physical and oceanographic facts as straightened out in the Encyclopedia of Coastal Science [6].","PeriodicalId":308766,"journal":{"name":"Oceanography & Fisheries Open access Journal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133206517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
