The radiometer wet tropospheric correction is a limiting factor of the application of near-coastal altimetry observations in the North Sea – Baltic Sea area. Using an ECMWF model based correction instead, we increase the return rate from 70% to 95%, with observations as close as 10 km from the coast. The altimetry and 39 coastal tide gauges are referenced to the same state of the art regional g...

The Wisconsin glaciation was started a approximately 125,000 years ago and reached its lowest extend between 20,000 to 21,000 years ago during which the sea level fell 120 to 130 meter. At the end of the ice age, about 18,000 years ago, the sea level increased and reached its present level about 5,000 years ago. The Persian Gulf was exposed in the last glacial moment (LGM). After this moment, t...

The author analyzes the materials of hydrological and archaeological research examines historical processes that took place in Volga River delta Middle Ages. Modern data on hydrology Caspian Sea, changes its water level, area mirror land are presented. A detailed schedule level Sea time interval 7th– 15th centuries is given, which allows us to identify favorable periods for human economic activ...

Sakarya River, which is the largest river in northwest Anatolia, drains waters from a large area known as Middle Plateau. The most striking geomorphological features of and its tributaries this area, are joining gorges connect basins terrace systems together. This study aims to reveal morphometric sedimentological between Inhisar, Gemiciköy settlements. has settled region Upper Pliocene, formed...

Genetic diversity is a key component of ecosystems. The aim of the present study was to evaluate the genetic diversity of Iranian native honeybee colonies (Apis mellifera meda L.) located in the northern region. Colonies from 24 locations have been analyzed using microsatellite markers. Samples were collected from Caspian Sea southern area (north of Iran). Six microsatellite markers (A28, A29, ...

This study provides the first in depth assessment of Sea Otter haul-out patterns in Elkhorn Slough, California and their relationship to environmental variables. Seasonal and daily water and air temperature fluctuations are a good predictor of Sea Otter haul-out patterns but are affected by the availability of haul-out sites at different tide levels. The cost effectiveness of this choice may be...

Sixty-four surface samples from the Lower Palaeozoic rock units (mainly Lalun,Abastu and Abarsaj formations) near Kholin-Darreh village in the Fazel Abad area,southeastern the Caspian Sea, Northern Iran, were analyzed to determine their agerelationships. The samples of Lalun Formation were barren, but those of Abastu andAbarsaj formations contained well-preserved and abundant palynomorph entiti...
