the main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the qeshm channel. for this purpose, the curves of the pressure on the persian gulf and oman sea, during the passing of the atmospheric low pressure system, are extracted across the region. during the time of occurrence of these events, sea level oscillations in the coastal areas of...

Harbor Seals (Phoca vitulina) are the most abundant and widespread seal species in Washington State. Most seal haul-out sites are unavailable at high tide, hence abundance estimates are conducted at low tide when it is commonly accepted that most seals are hauled-out. On sites unaffected by tides, however, it is less clear whether tide level has an effect on seal abundance. We counted hauled-ou...

This study investigated the phenology, patterns of haul-out habitat use and distribution of the grey seal around Cornwall and the Isles of Scilly. A full census of the coast was carried out by boat over 4 days, in order to make a full count of seals hauled out and close to the coast, and to document all haul-out sites. Regular land-based surveys were made of three haul-out sites in Cornwall, to...

based on 11 years of topex/poseidon satellite altimetry and coastal tide gauge sea level observations, four tidal constituents, namely o1, k1, m2 and s2, are modeled for the persian gulf and oman sea using a time-wise approach according to the following details. by selecting the cycle 100 as the reference, 772 points on 12 paths along the track of the altimetry satellite footprints over the per...

Variation was investigated at exon 2 (including part of the putative peptide-binding region) of the class II major histocompatibility complex (MHC) DQB locus for two congeneric phocid seal species and two congeneric otariid seal species. Polymorphism in one phocid species, the southern elephant seal (Mirounga leonina), was comparable to that seen in human populations, while the other phocid, th...
