Abstract Arctic warming accelerates permafrost thaw and coastal erosion, increasing terrestrial material transport to the ocean. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data (2002–2023), we report a widespread increase in the diffuse attenuation coefficient Kd(490) across Arctic shelves since 2018, notably in the Laptev and Kara ...

Abstract What is the relative importance of variability in local evaporation versus moisture convergence from lower latitudes to changes in autumn/winter Arctic Ocean precipitation? Past research has offered sometimes contradictory answers. Here we offer some resolution to this question by addressing two research gaps.

Combining individual and close‐kin mark–recapture to design an effective wildlife population survey
Abstract Close‐kin mark–recapture (CKMR) is a promising approach for assessing population size of species that have been difficult to survey using more traditional methods. Here, we combine individual and close‐kin mark–recapture in a single modeling framework (ICKMR) and provide an example of study design using this approach for Pacific walrus ...

Diving deep into the origins of refractory dissolved amino acids in the ocean
Abstract Amino acids are key constituents of marine peptides and proteins and are generally considered biologically labile or semi‐labile, yet their widespread occurrence throughout the ocean suggests bioresistance over extended timescales. To investigate this paradox, we conducted two parallel shipboard incubation experiments to track microbial ...

Abstract We present a data set of macronutrient and dissolved and total dissolvable trace metal concentrations collected in June 2012 across the Nordic Seas. Surface water and depth profiles of manganese, iron, cobalt, nickel, copper, zinc, phosphate, silicic acid, and NOx (nitrate + nitrite) reveal how warm saline Atlantic waters and cold fresh Arctic
