Here we report the first optical, sensor-based profiles of nitrate from the central Makarov and Amundsen and southern Canada Basins of the Arctic Ocean. These profiles were obtained as part of the International Polar Year program during spring 2007 a

Concentrations of dissolved and particulate Cd, Cu, Pb and Zn were determined in samples collected in summer 1998 from the lower reaches of six major Eurasian arctic rivers: the Onega, Severnaya Dvina, Mezen, Pechora, Ob and Yenisey. These data compr

Distributions of temperature, salinity, and barium in near-surface waters (depth ≤ 50 m) of the Laptev Sea and adjacent areas of the Arctic Ocean are presented for the summers of 1993, 1995, and 1996. The tracer data indicate that while fluvial dis

Here we report results from an extensive survey of dissolved organic carbon (DOC) in the Arctic Ocean, which was achieved by means of a high-resolution, in situ UV fluorometer deployed on a nuclear submarine. Based on a strong linear correlation obse

Analyses for dissolved Ba have been performed on water samples obtained from the estuaries of major Arctic rivers and adjacent seas between 1993 and 1996. Complex behavior was observed in the mixing zones between fluvial and oceanic waters. In these

Dissolved barium (Ba) concentrations are reported for water samples collected during six oceanographic cruises to the Arctic in 1993 and during the 1994 Arctic Ocean Section. Upper Arctic ( -75 nmol Ba 1−1) observed in the surface mixed layer of th

[1] The utility of dissolved barium (Ba) as a quasi-conservative tracer of Arctic water masses has been demonstrated previously. Here we report distributions of salinity, temperature, and Ba in the upper 200 m of the Canada Basin and adjacent areas o

More than 10% of all continental runoff flows into the Arctic Ocean. This runoff is a dominant feature of the Arctic Ocean with respect to water column structure and circulation. Yet understanding of the chemical characteristics of runoff from the pa

The gastrulating chick embryo expresses two galactoside-binding lectins of 14 kDa and 16 kDa. These lectins are present in the area pellucida and area opaca, and in the latter are concentrated in the endoderm. Since the area opaca is the progenitor o
