Sea surface temperature (SST), salinity, and chlorophyll concentration (CHL) have changed in the US Northeast Shelf ecosystem over recent decades. The changes in these parameters were distinctly marked by change points around the year 2012 resulting in a 0.83°C increase in SST, a 0.3 PSU increase in salinity, and decrease in CHL in excess of 0.4 mg m–3. Where temperature and salinity shifted in mean level around their respective change points, CHL declined in a more monotonic fashion. Modeled…

The impact of oyster aquaculture on the estuarine carbonate system
Many studies have examined the vulnerability of calcifying organisms, such as the eastern oyster (Crassostrea virginica), to externally forced ocean acidification, but the opposite interaction
Northern shrimp Pandalus borealis population collapse linked to climate-driven shifts in predator distribution
TLDR
It is hypothesized that the warmer temperatures of 2012 not only led to expansion of longfin squid distribution in Gulf of Maine, but had differential effects on migration phenology that further increased spatial overlap with northern shrimp.
COI Metabarcoding of Zooplankton Species Diversity for Time-Series Monitoring of the NW Atlantic Continental Shelf
Marine zooplankton are rapid-responders and useful indicators of environmental variability and climate change impacts on pelagic ecosystems on time scales ranging from seasons to years to decades.

Changes in phytoplankton community structure during wind-induced fall bloom on the central Chukchi shelf
TLDR
It is concluded that SWEs during fall might affect food webs via the alternation of seasonal succession of phytoplankton community structure by weakening the stratification and enhancing diatom-derived pigment concentrations.

Evidence of bottom-up limitations in nearshore marine systems based on otolith proxies of fish growth
TLDR
Results are consistent with bottom-up forcing of nearshore marine ecosystems—light and nutrients constrain primary production in pelagic food webs, and temperature constrains benthic food webs.
Ocean colour signature of climate change
TLDR
It is shown that remote sensing reflectance (RRS), such as the ratio of upwelling versus downwelling light at the ocean’s surface, has a stronger and earlier climate-change-driven signal over the 21st century.
Satellite Observations of Phytoplankton Functional Type Spatial Distributions, Phenology, Diversity, and Ecotones
TLDR
High levels of diversity were observed in the tidally well-mixed regions of the Gulf of Maine and along a band that ran along the shelf region of the study area that was narrowest in the summer periods and broadened during the winter.
