Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

Land Degradation &Development, EarlyView.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Validation of Ocean Color Remote Sensing Reflectance Using Autonomous Floats

Journal of Atmospheric and Oceanic Technology, 2016
AbstractThe use of autonomous profiling floats for observational estimates of radiometric quantities in the ocean is explored, and the use of this platform for validation of satellite-based estimates of remote sensing reflectance in the ocean is examined.

Sediment trap preservative choice impacts particle‐associated microbial community composition

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding and quantifying the microbial contribution to particulate organic matter (POM) flux and carbon cycling in the ocean relies largely on the collection of sinking POM. A critical aspect of evaluating microbial communities on sediment trap‐collected POM is their preservation until recovery and sample processing.

Satellite Ocean Color Sensor Design Concepts and Performance Requirements [PDF]

In late 1978, the National Aeronautics and Space Administration (NASA) launched the Nimbus-7 satellite with the Coastal Zone Color Scanner (CZCS) and several other sensors, all of which provided major advances in Earth remote sensing. The inspiration for

The IceShark, an effective method for sampling plankton under sea ice

Limnology and Oceanography: Methods, EarlyView.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Technique for validating remote sensing products of water quality [PDF]

, 2008
Remote sensing of water quality is initiated as an additional part of the on going activities of the EAGLE2006 project. Within this context intensive in-situ and airborne measurements campaigns were carried out over the Wolderwijd and Veluwemeer ...

Challenges and New Advances in Ocean Color Remote Sensing of Coastal Waters [PDF]

, 2013
Knowing that coastal areas concentrate about 60% of the world's population (within 100 km from the coast), that 75-90% of the global sink of suspended river load takes place in coastal waters in which about 15% of the primary production occurs, the ecological, societal and economical value of these areas are obvious (fish resources, aquaculture, water ...

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

Limnology and Oceanography: Methods, EarlyView.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...
