Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat, A Proof of Concept [PDF]

, 2017
Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefore drifted and rocked.

Optimizing Plankton Image Classification With Metadata-Enhanced Representation Learning

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Automated camera-based sensors are widely used in vessel-based research to monitor plankton and marine particles. However, current methods suffer from the costly and time-consuming requirement of annotating data for fully supervised learning, especially ...

Machine Learning for the Study of Plankton and Marine Snow from Images.

Annual Review of Marine Science, 2021
Quantitative imaging instruments produce a large number of images of plankton and marine snow, acquired in a controlled manner, from which the visual characteristics of individual objects and their in situ concentrations can be computed.

Marine gravity image available

Eos, Transactions American Geophysical Union, 1994
The image below shows the gravity field from 30–72°S computed from Geosat geodetic mission (GM) and exact repeat mission (ERM) data. A color shaded‐relief image of these gravity anomalies is available from NOAA in poster form (report MGG‐8, [Marks et al., 1993] and also as a digital gridded data set on CD‐ROM. To order, contact the National Geophysical

Marine biofouling resistance rating using image analysis

Journal of Coatings Technology and Research, 2022
Biofouling on ship hulls can cause increased fuel consumption and the global spread of nonindigenous species. The shipping industry utilizes fouling control coatings (FCC) to prevent biofouling from occurring on the ship hull. The evaluation standards for the performance of FCC are based on manual inspections, which unavoidably induce some degree of ...

Cell lineage and cell cycling analyses of the 4d micromere using live imaging in the marine annelid Platynereis dumerilii

eLife, 2017
Cell lineage, cell cycle, and cell fate are tightly associated in developmental processes, but in vivo studies at single-cell resolution showing the intricacies of these associations are rare due to technical limitations.
