Introduction: The Kara River basin, located between the Pai-Khoi ridge and the Baydarata Gulf of the Kara Sea 200 km to the north of Vorkuta, Russia, was found to be an impact structure in 1970’s [1,2]. The 40Ar-39Ar impactite ages vary from 70 to 75 Ma [3,4]. Actually, two craters were suggested [1]: The Kara crater, 60-65 km in diameter, was defined on the Kara River estuary while the 25 km U...

Based on Moderate Resolution Imaging Spectoradiometer (MODIS) remote sensing data, meteorological observation multisource atmospheric circulation, and sea surface temperature (SST) data from NCEP/NCAR reanalysis, we estimated the net primary productivity (NPP) of terrestrial natural vegetation in China according to CASA model analyzed linear trend interannual fluctuation NPP, as well spatial di...

BACKGROUND Drowning is a serious but neglected health problem in low-and middle-income countries. OBJECTIVES To describe the effectiveness of drowning prevention program on the reduction of drowning mortality rates in rural settings at the north of Iran, and guide its replication elsewhere. PATIENTS AND METHODS This interventional design included pre- and post-intervention observations in t...

The determination of the value of sea area used for port transportation involves the distribution of economic interests between the Chinese government and the users of sea areas. This paper builds an evaluation index system for the value of port transport sea areas. It is the first of its type to introduce the multiple regression weighting TOPSIS method (Technique for Order Preference by Simila...

[1] Enhanced resolution Advanced Microwave Scanning Radiometer (AMSR-E) imagery is used to estimate daily sea ice area fluxes between the Canadian Arctic Archipelago and the Arctic Ocean and Baffin Bay for the period September 2002 to June 2007. Over the period, Amundsen Gulf and M’Clure Strait exported 54 10 km of sea ice area or roughly 77 km of sea ice volume each year into the Arctic Ocean....

Equatorward sea ice drift can have competing impacts on the cover. On one hand, as reaches warmer waters it will be subject to faster melt. other near pole thin, causing growth when air temperatures are below freezing. This prompts fundamental question whether equatorward motion increases or decreases area and volume? We investigate this using an idealized climate model with a representation of...

Arctic sea ice area has been decreasing for the past two decades. Apart from melting, the southward drift through Fram Strait is the main ice loss mechanism. We present high resolution sea ice drift data across 79 N from 2004 to 2010. Ice drift has been derived from radar satellite data and corresponds well with variability in local geostrophic wind. The underlying East Greenland current contri...

Uranium-series dating of corals from marine deposits of the U.S. Atlantic Coastal Plain coupled with paleoclimatic reconstructions based on ostracode (marine) and pollen (continent) data document at least five relatively warm intervals during the last 500,000 years. On the basis of multiple paleoenvironmental criteria, we determined relative sea level positions during the warm intervals, relati...
