Abstract A major surface circulation feature of the Arctic Ocean is Transpolar Drift (TPD), a current that transports river‐influenced shelf water from Laptev and East Siberian Seas toward center basin Fram Strait. In 2015, international GEOTRACES program included high‐resolution pan‐Arctic survey carbon, nutrients, suite trace elements isotopes (TEIs). The cruises bisected TPD at two locations in central basin, which were defined by maxima meteoric dissolved organic carbon concentrations...
High-albedo white and cool roofing membranes are recognized as a fundamental strategy that dense urban areas can deploy on large scale, at low cost, to mitigate the heat island effect. We monitoring three generic within New York City represent cross section of dominant membrane options for US flat roofs: (1) an ethylene–propylene–diene monomer (EPDM) rubber membrane; (2) thermoplastic polyolefin (TPO) (3) asphaltic multi-ply built-up coated with elastomeric acrylic paint. The paint product...
Abstract The physical and biogeochemical properties of the western Arctic Ocean are rapidly changing, resulting in cascading shifts to local ecosystems. nutrient‐rich Pacific water inflow through Bering Strait is modified on Chukchi East Siberian shelves by brine rejection during sea ice formation, a strong halocline (called Upper Halocline Layer (UHL)) that separates cold relatively fresh surface layer from warmer more saline (and nutrient‐poor) Atlantic‐derived below. Biogeochemical...
Early studies revealed relationships between barium (Ba), particulate organic carbon and silicate, suggesting applications for Ba as a paleoproductivity tracer of modern ocean circulation.
Abstract Determining the proportions of Atlantic and Pacific Ocean seawater entering Arctic is important both for understanding mass balance this basin as well its contribution to formation North deep water. To quantify distribution amount origin in western Ocean, we used dissolved Ga a four‐component linear endmember mixing model. Previously, nutrients, combined their Redfield ratios, have been separate Pacific‐ Atlantic‐derived waters. These nutrient tracers are not conservative practice,...
Abstract This study traces dissolved organic matter (DOM) in different water masses of the Arctic Ocean and its effect on distributions trace elements (TEs; Fe, Cu, Mn, Ni, Zn, Cd) using fluorescent properties DOM terrigenous biomarker lignin. The Nansen, Amundsen, Makarov Basins were characterized by influence Atlantic fluvial discharge Siberian Rivers with high concentrations (tDOM).

Abstract In this contribution, we present tritium‐3He ( 3 H‐ He) apparent ages and hydrographic data from 21 expeditions spanning 27 years of Arctic Ocean section work (1987–2013) to estimate flow paths spreading velocities the Atlantic Waters (AW) circulation on a pan‐Arctic scale. Tracer not only corroborate well‐organized cyclonic along continental slope but also introduce temporal dimension these observations. Additionally, they provide insights into other branches layer, which are...
In this contribution we present tritium-3He (3H-3He) apparent ages and hydrographic data from 21 expeditions spanning 27 years of Arctic Ocean section work (1987 to 2013) estimate flow paths spreading velocities the Atlantic Waters (AW) circulation on a pan-Arctic scale. Tracer independently reveal add time dimension well-organized boundary current that cyclonically flows along continental slope insights into other branches layer, hypothesized be guided by deep topography (Rudels, et al.,...
