Long‐term chronologies constructed from individual bowhead baleen plates reveal stable isotope declines consistent with regional Arctic food web or productivity changes superimposed on global anthropogenic C and N inputs, while relatively stable hormone concentrations over the same period provide no evidence of a concomitant increase in physiological ...

Abstract Linear regressions between total alkalinity (TA) and dissolved inorganic carbon (DIC) are widely used to infer the balance between net ecosystem calcification (NEC) and net ecosystem production (NEP) in coral reefs. Using high‐frequency carbonate chemistry observations from an Australian reef flat and simple numerical models, we show that TA ...

Abstract The Arctic Ocean has experienced intensifying phytoplankton spring blooms near the sea ice edge. Here, we investigate the drivers of such near‐ice blooms in the Greenland Sea by comparing satellite and in situ observations with the ECCO‐Darwin physical–biogeochemical state estimate.

Abstract Chlorophyll a (Chl a) is a key indicator of phytoplankton biomass and marine primary productivity, linking ocean ecosystem change to biogeochemical cycling and climate. Understanding the environmental controls on long‐term Chl a variability is therefore essential.

The Role of Bubbles in Air‐Sea Gas Exchange: A Critical Review
Abstract Air‐sea gas exchange regulates the exchange of climatically important gases between the ocean and the atmosphere, shaping both climate and ocean biogeochemistry. Bubbles beneath the sea surface enhance this exchange by introducing an additional transfer pathway in parallel to the interfacial transfer route.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Enhanced Subsurface Warming of the Kuroshio Revealed by Long‐Term Observations During 1965–2020
Abstract The Kuroshio transports large amounts of heat from the tropical to extratropical Pacific, playing a crucial role in regional climate changes. However, how the temperature and heat transport changes of the Kuroshio under a warming climate remain ambiguous.

Persistent Shelf‐to‐Basin Export of Bioavailable Dissolved Organic Carbon in the Arctic Ocean
Abstract Microbial carbon demand often exceeds local primary production in the oligotrophic central Arctic Ocean. Whether shelf‐derived dissolved organic carbon (DOC) provides a persistent carbon subsidy to reconcile this imbalance remains unclear. Here, we combine amino acid‐based molecular tracers and hydrographic analyses to trace the transport and ...

Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set records direct sampling of total atmospheric deposition from March 2015 to ...

Abstract Submarine groundwater discharge (SGD), an important component of coastal water and nutrient budgets, is challenging to monitor and predict in the Arctic given the remoteness and harsh conditions. Here, we used explainable artificial intelligence to quantify the time‐varying importance of hydroclimatic and oceanic drivers of SGD at an Arctic ...
