Satellite‐Observed Hourly Chlorophyll Variability Associated With Solar Radiation in China's Marginal Seas

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Understanding sub‐daily variability in phytoplankton proxies is essential for interpreting satellite estimates of ocean productivity in marginal seas. Using high‐frequency observations from the Geostationary Ocean Color Imager (GOCI), we assess daytime (08:00–15:00 local time) hourly surface chlorophyll‐a (Chla) variability across China's ...

Colored dissolved organic matter (CDOM) and dissolved organic carbon (DOC) measured during helicopter/ice camp TRANSDRIFT-XX, Laptev Sea

, 2020
The data set includes the light absorption coefficient of colored dissolved organic matter (CDOM) from 200 nm to 700 nm wavelength and dissolved organic carbon (DOC) from the land-fast ice in the Laptev Sea. Sampling was carried out March and April 2012.

Key considerations for the use of satellite‐based remote sensing for lake and reservoir research and management

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract Given the critical importance of freshwater for human well‐being and the myriad threats altering water quality and quantity, monitoring lakes and reservoirs is necessary to identify where, how, and why freshwater ecosystems are changing globally.

Iron influence on dissolved color in lakes of the Upper Great Lakes States.

PLoS ONE, 2019
Colored dissolved organic matter (CDOM), a major component of the dissolved organic carbon (DOC) pool in many lakes, is an important controlling factor in lake ecosystem functioning. Absorption coefficients at 440 nm (a440, m-1), a common measure of CDOM,

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Stable Sediment Plumes Despite Tidewater Glacier Retreat in a South Greenland Fjord

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Tidewater glaciers play a critical role in ice sheet mass loss and fjord hydrography, as meltwater runoff volume and injection depth can influence sediment transport, fjord circulation, and fjord stratification. As tidewater glaciers retreat and transition from marine‐ to land‐terminating, the impacts of shifting meltwater delivery depth on ...

Fluorescence measurements of colored dissolved organic matter (cDOM) in Pohjanpitäjänlahti bay in May 2021

, 2022
Water samples were collected from Pohjanpitäjänlahti bay in May 2021 from four stations along a coastal salinity gradient. Fluorescence was measured and T-, A-, M- and C-peaks as well as humification, biological and fluorescence indices were calculated ...

Contribution to a bio-optical model for remote sensing of Lena River water [PDF]

Biogeosciences, 2013
Bio-optical measurements and sampling were carried out in the delta of the Lena River (northern Siberia, Russia) between 26 June and 4 July 2011. The aim of this study was to determine the inherent optical properties of the Lena water, i.e., absorption,

Quantifying Shifts in the Absorption Budget of the Labrador Sea as the Dominant Phytoplankton Group Changes Between Diatoms and Phaeocystis

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Phytoplankton spring blooms in the Labrador Sea are dominated by diatoms, with Phaeocystis spp. (hereafter Phaeocystis) contributing more than 25% to total phytoplankton biomass. However, in 2015 and 2022, large blooms of Phaeocystis were observed, contributing up to 90% of the surface phytoplankton biomass. In this study, we quantified shifts
