Abstract We stand at the threshold of a transformative era in Earth observation, marked by space‐borne visible‐to‐shortwave infrared (VSWIR) imaging spectrometers that promise consistent global observations ecosystem function, phenology, and inter‐ intra‐annual change. However, full value repeat spectroscopy, information embedded within different temporal scales, reliability existing algorithms across diverse types vegetation phenophases have remained elusive due to absence suitable...
The U.S. Northeast Continental Shelf is experiencing rapid warming, with potentially profound consequences to marine ecosystems. While satellites document multiple scales of spatial and temporal variability on the surface, our understanding status, trends, drivers benthic environmental change remains limited. We interpolated sparse temperature data along New England upper Slope using a seasonally dynamic, regionally specific linear regression model that merged in situ remote sensing data....
Coastal water clarity varies at high temporal and spatial scales due to weather, climate, human activity along coastlines. Systematic observations are crucial assessing the impact of change on aquatic habitats. In this study, Secchi disk depths (ZSD) from Boston Harbor, Buzzards Bay, Cape Cod Narragansett Bay quality monitoring organizations were compiled validate ZSD derived Landsat 8 (L8) imagery, generate resolution maps. From 58 L8 images, acceptable agreement was found between in situ...
Abstract National Aeronautics and Space Administration's Orbiting Carbon Observatory‐2 (OCO‐2) satellite provides observations of total column‐averaged CO 2 mole fractions ( ) at high spatial resolution that may enable novel constraints on surface‐atmosphere carbon fluxes. Atmospheric inverse modeling an approach to optimize surface fluxes regional scales, but the accuracy from inversion frameworks depends key inputs, including spatially temporally dense reliable representations atmospheric...
The Arctic and Subarctic seas are predicted to become hotspots for marine heatwaves (MHWs). High-latitude ecosystems face unique consequences from accelerated warming sea ice loss, challenging species adapted cold conditions. We review the literature on MHW characteristics ecological impacts in seas, contrast between Bering Sea Barents Sea. uncover pervasive of MHWs across widely different organism groups, including benthic foundation species, phytoplankton, zooplankton, fish, seabirds,...
Abstract Understanding and attributing changes to water quality is essential the study management of coastal ecosystems ecological functions they sustain (e.g., primary productivity, predation, submerged aquatic vegetation growth). However, describing patterns clarity—a key aspect quality—over meaningful scales in space time challenged by high spatial temporal variability due natural anthropogenic processes. Regionally tuned satellite algorithms can provide a more complete understanding...
Abstract The Woods Hole Partnership Education Program (PEP) has provided a 10‐week residential summer internship program for underrepresented minorities since 2009. Six weeks prior to the planned 2020 program, gravity of COVID‐19 pandemic prompted unanimous decision PEP leadership and staff deliver virtual program. However, this engendered new set considerations successful undergraduate research In article, we discuss how its partner institutions galvanized around PEP's overarching goals...
Abstract Phytoplankton primary production is a crucial component of Arctic Ocean (AO) biogeochemistry, playing pivotal role in carbon cycling by supporting higher trophic levels and removing atmospheric dioxide. The advent satellite observations measuring chlorophyll concentration (Chl_a) has provided unprecedented insights into the distribution AO phytoplankton, enhancing our ability to assess oceanic net (NPP). However, optical properties waters differ significantly from those...
Radiative transfer modeling of Secchi disk observations has historically been based on conjugated signals eye response and radiance, where water's attenuation in the entire visible band is included when deciding depth water. Aas et al. [Ocean Sci.10(2), 177 (2014)Remote Sens. Environ.169, 139 (2015)] hypothesized that it actually transparent window matters to observation a To test this hypothesis, disks blue green waters were conducted via naked eyes, blue-pass glasses, green-pass glasses....
For the first time vertical variation in light quality global ocean is quantified with a single parameter—the hue angle ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\alpha _{E}$ </tex-math></inline-formula> , degree) chromaticity of downwelling irradiance. oceanic waters, ~140° at surface, but it becomes ~230° bottom euphotic zone; changes rapidly near and we term this layer rapid change as...
Abstract The risks harmful algal blooms (HAB) pose to aquatic ecosystems, public health, and coastal economies necessitate supplementation of current observation strategies. Herein, we explore the use red solar induced fluorescence (SIF) from TROPOspheric Monitoring Instrument (TROPOMI), a remote sensing measurement retrievable in variable cloud conditions, for Karenia brevis detection. Along West Florida Shelf 2018 2020, compare SIF with normalized line height (nFLH) MODIS‐Aqua, standard...
For waters with stratified chlorophyll concentration (Chl), numerical simulations were carried out to gain insight into the forward models of subsurface reflectance and empirical algorithms for Chl from ocean color. It is found that Gordon Clark (1980) model using an equivalent homogeneous water a weighted average ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mo fence="false" stretchy="false">⟨<!-- ⟨ --></mml:mo> <mml:mrow class="MJX-TeXAtom-ORD"> <mml:mi...
Phytoplankton primary production is a crucial component of Arctic Ocean (AO) biogeochemistry, playing pivotal role in the carbon cycling by supporting higher trophic levels and removing atmospheric dioxide. The advent satellite observations measuring chlorophyll concentration (Chl_ a) has yielded unprecedented insights into distribution AO phytoplankton, enhancing our ability to assess oceanic productivity.

The Arctic is warming four times faster than the global average, resulting in widespread ground thaw and state changes. Due to rapid rate large scale of ecosystem shifts, identifying understanding boreal zone changes feedbacks requires frequent observations across multiple scales. last decade has witnessed significant increases number coverage in-situ, airborne, satellite observations.

Abstract The onset of the COVID‐19 pandemic and Black Lives Matter movement urged institutions to redress shortcomings in their diversity, equity, inclusion goals initiatives. School for Environment (SFE) at University Massachusetts Boston (UMass Boston), a public research minority serving university United States America, responded this call through launching Online Conversations Equity, Action, Networking (OCEAN) program. This pilot project funded by Woods Hole Sea Grant aimed amplify...
