Concentrations of Multiple Phytoplankton Pigments in the Global Oceans Obtained from Satellite Ocean Color Measurements with MERIS

open access: yesApplied Sciences, 2018
The remote sensing of chlorophyll a concentration from ocean color satellites has been an essential variable quantifying phytoplankton in the past decades, yet estimation of accessory pigments from ocean color remote sensing data has remained largely ...

Optimizing stereo‐baited remote underwater video sampling efficiency in turbid waters through horizontal field of view adjustments

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate length data underpin many ecological and physiological analyses, from assessing population size structure to parameterizing biomass and bioenergetic models. Stereo‐baited remote underwater video systems (stereo‐BRUVs) provide a non‐intrusive means of collecting these data in situ, supporting management and conservation of motile ...

Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies

open access: yesLaser &Photonics Reviews, EarlyView.
We introduce 3D nanoprinting of gold nanoparticle assemblies and show that their broad optical responses remain reproducible despite structural disorder. This robustness is attributed to ensemble‐averaged plasmonic responses from many local coupling regions.

Evaluation of Four Atmospheric Correction Algorithms for GOCI Images over the Yellow Sea

open access: yesRemote Sensing, 2019
Atmospheric correction (AC) for coastal waters is an important issue in ocean color remote sensing. AC performance is fundamental in retrieving reliable water-leaving radiances and then bio-optical parameters.

Ocean Color Remote Sensing of Phytoplankton Functional Types

open access: yes, 2012
Interest in phytoplankton diversity has increased in recent years due to its possible role in regulating climate by production and consumption of greenhouse gases. For example, gases can diffuse across the air-sea interface, many of which are synthesized and emitted by certain phytoplankton species or groups. It has been suggested that these variations

Digital surveillance of animals and nature recovery

open access: yesPeople and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

High-resolution ocean color imagery from the SeaHawk-HawkEye CubeSat mission

open access: yesScientific Data
Here we describe the data obtained by a successful proof-of-concept initiative to launch the first ocean color imager on board a CubeSat satellite and collect research-grade imagery at severalfold higher spatial resolution than any other ocean color ...

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

An extensive validation of ocean color products for the black sea

open access: yesGIScience & Remote Sensing
Ocean color remote sensing provides an efficient approach to monitor the state and changes in water bodies on Earth. The validation of an ocean color product is a key step in assessing its accuracy, directly influencing the confidence with which ...
