On sources and sinks of bioavailable nitrogen on the Scotian Shelf: Insights from nutrient distributions and nitrate isotope ratios

Autor: Nadine Lehmann, Markus Kienast, Claire Normandeau, Peter Thamer, Carolyn Buchwald

The northwestern North Atlantic, and the extensive Northwest Atlantic Shelf in particular, are among the areas of the world’s ocean most dramatically affected by ongoing climate change. Profound alterations of nitrogen (N) cycling both in the water

Publikováno v: Quaternary Science Reviews. 30:210-223

In this study, we use records of nitrogen isotope ratios (δ15N), UK’37 temperature estimates, organic carbon and opal percentages from high-resolution sediment cores located in the eastern equatorial Pacific (EEP) to explore the mechanisms linking

Eastern equatorial Pacific cold tongue during the Last Glacial Maximum as seen from alkenone paleothermometry

Publikováno v: Paleoceanography. 24

[1] We present new alkenone-based sea surface temperature (SST) estimates from the eastern equatorial Pacific (EEP) for the last 30 kyr. By combining these new results with recently published records from the region, we reconstruct the spatial patter
