Procedures are developed for calculating effects of western boundaries of arbitrary geometry on low-frequency equatorial waves. We show that the mass flux incident at the coast is all returned eastward by equatorial Kelvin waves. Short Rossby waves generated as part of the reflection serve only to redistribute mass along the coast. For the case of a uniformly sloping coast we present formulae a...

The Atlantic Forest is represented on the coast of Brazil by approximately 7.5% of remnants, much of these concentrated on the country's SE coast. Within these southeastern remnants, we still find the coastal Caiçaras who descend from Native Indians and Portuguese Colonizers. The maintenance of such populations, and their existence in spite of the deforestation that occurred on the Atlantic For...

the levels of 19 organochlorine pesticides (ocps) in surface water and under water sedimentsfrom tanks located nearby the prime agricultural areas of kanyakumari district, tamil nadu, india wereinvestigated to evaluate their pollution risks. a total of 36 surface water samples at 9 sampling sites and27 sediment samples at 9 sampling stations were collected from tanks, which were the water sourc...

An integrative conflict analysis approach, incorporating an Analytic Hierarchy Process (AHP) based preference ranking method into the Graph Model for Conflict Resolution (GMCR), is employed to investigate the Canadian west coast port congestion dispute. The Canadian west coast has historically been an important gateway connecting North America to Asia thanks to its specific geographical and str...

The displacement pattern of the serra, Scomberomorus brasiliensis, in North-eastern Brazil was analyzed from landing data recorded form the fleet fishing serra. Serra fishery has two seasons: from Septemer to February (demersal species plus serra), and from March to August (almost only large amounts of serra). S. brasilienisis relative abundance increases similarly along the coast from March. b...

The damage scale and damage area in the coast have been increased dramatically because of calamities such as typhoon, tidal wave, flood and storm. Especially, 409 cases, which reach to about 40.9% of natural disasters of 1,000 cases for the recent 15 years have happened on coast area. More than 40% of natural disasters also occurred every year is happening in coastland. Therefore, there is a gr...

In the present study, marine crab Portunuspelagicus was screened with 17 primers and made to score polymorphism. The main emphasis of study assess genetic diversity at intra specific level among 3 accessions P. pelagicus species Gulf Mannarusing RAPD markers. analysis shows that there is a high polymorphism different accessions. From this it understood each location varied respect environmental...

Two new species of the genus Hydrometra Latreille, 1796, are described from the Oriental Region. Hydrometra cherukolensis sp. nov. is described from Kanyakumari District, Tamil Nadu, India, belongs to the Hydrometra julieni species group, and is closely related to H. julieni Hungerford & Evans, 1934 and H. julienoidea Polhemus & Polhemus, 1995. Hydrometra nicobarensis sp. nov. is described from...

Tar ball (TB) deposition along the West Coast of India (WCI) is a common phenomenon during the southwest monsoon season, particularly along the coast of Goa and Gujarat, and it is a major concern to the stake holders. Our earlier studies showed that the source oil for the TBs deposited on the Goa coast in August 2010 is the tanker wash, and the source for subsequent TBs deposited on the Gujarat...
