Global trends of ocean warming, deoxygenation, and acidification are not easily extrapolated to coastal environments. Local factors, including intricate hydrodynamics, high primary productivity, freshwater inputs, and pollution, can exacerbate or attenuate global trends and produce complex mosaics of physiologically stressful or favorable condition...
The efficacy of marine protected areas (MPAs) may be reduced when climate change disrupts the ecosystems and human communities around which they are designed. The effects of ocean warming on MPA functioning have received attention but less is known about how multiple climatic stressors may influence MPAs efficacy. Using a novel dataset incorporatin...

Local factors, including intricate hydrodynamics, high primary productivity, freshwater inputs, and pollution, can exacerbate or attenuate global trends and produce complex mosaics of physiologically stressful conditions for org...
In the United States, domestic oyster aquaculture production is insufficient to meet national demand, thus creating a reliance on international oyster imports for consumption. West coast shellfish farmers are threatened by climate change, including ocean acidification as well as socioeconomic challenges such as labor availability. To expand and enh...
This document articulates a multi-faceted and multi-partner Roadmap to Recovery (Roadmap) for the sunflower sea star (Pycnopodia helianthoides) along the West Coast of North America. The species has experienced catastrophic declines across much of its range, principally due to sea star wasting disease. This Roadmap provides an overview of key near-...
Kelp forests line a quarter of the world’s coastlines and provide diverse ecosystem services. While kelps are a harvested resource themselves, they are also foundation species that form the basis of productive ecosystems. Globally, kelps are threatened by a variety of anthropogenic impacts, including overharvesting, overgrazing, invasive species, p...
Surface-canopy forming kelps provide the foundation for ecosystems that are ecologically, culturally, and economically important. However, these kelp forests are naturally dynamic systems that are also threatened by a range of global and local pressures. As a result, there is a need for tools that enable managers to reliably track changes in their...
The prevalence of disease-driven mass mortality events is increasing, but our understanding of spatial variation in their magnitude, timing and triggers are often poorly resolved. Here, we use a novel range-wide dataset comprised 48 810 surveys to quantify how sea star wasting disease affected Pycnopodia helianthoides , the sunflower sea star, acro...
A critical tool in assessing ecosystem change is the analysis of long‐term data sets, yet such information is generally sparse and often unavailable for many habitats. Kelp forests are an example of rapidly changing ecosystems that are in most cases data poor. Because kelp forests are highly dynamic and have high intrinsic interannual variability,...
As 2020 approaches, countries are accelerating their commitments to protect 10% of the ocean by establishing and expanding marine protected areas (MPAs) and other area-based protections. Since it began in 2014, the Our Ocean Conference (OOC) has become a high-profile platform to announce ocean commitments. To evaluate the impact of these promises,...
Small pelagic fishes represent a critical link between zooplankton and large predators. Yet, the
taxonomic resolution of the diets of these important fishes is often limited, especially in the Northwest
Atlantic. We examined in detail the diets, along with stable isotope signatures, of five dominant small
pelagic species of the northeast US contine...
Increased surface melt over the Greenland Ice Sheet (GrIS) is now estimated
to account for half or more of the ice sheet's total mass loss. Here, we
show that some meltwater is stored, over winter, in buried supraglacial
lakes. We use airborne radar from Operation IceBridge between 2009 and 2012
to detect buried supraglacial lakes, and we find that...
