Reduction of Rain-Induced Errors for Wind Speed Estimation on SAR Observations Using Convolutional Neural Networks

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Synthetic aperture radar (SAR) is known to be able to provide high-resolution estimates of surface wind speed. These estimates usually rely on a geophysical model function (GMF) that has difficulties accounting for nonwind processes, such as rain events.

Oceanic productivity and high-frequency temperature variability—not human habitation—supports calcifier abundance on central Pacific coral reefs

Frontiers in Marine Science, 2022
Past research has demonstrated how local-scale human impacts—including reduced water quality, overfishing, and eutrophication—adversely affect coral reefs. More recently, global-scale shifts in ocean conditions arising from climate change have been shown

First Insights Into the Horizontal Movements of Whale Sharks (Rhincodon typus) in the Northern Arabian Sea

Frontiers in Marine Science, 2021
Whale sharks off the western coast of India have suffered high levels of fishing pressure in the past, and today continue to be caught in small-scale fisheries as by-catch.

Physical oceanography [PDF]

, 1996
The physical oceanography component of the AMLR program provided the means to identify contributing water masses and environmental influences within the AMLR study area, as well as to log meteorological and sea surface conditions annotated by the ship's ...

A Primer on the Vertical Lagrangian‐Remap Method in Ocean Models Based on Finite Volume Generalized Vertical Coordinates

Journal of Advances in Modeling Earth Systems, 2020
This paper provides a primer on the mathematical, physical, and numerical foundations of ocean models that are formulated using finite volume generalized vertical coordinate equations and that use the vertical Lagrangian‐remap method to evolve the ocean ...

Using Saildrones to Validate Satellite-Derived Sea Surface Salinity and Sea Surface Temperature along the California/Baja Coast

Remote Sensing, 2019
Traditional ways of validating satellite-derived sea surface temperature (SST) and sea surface salinity (SSS) products by comparing with buoy measurements, do not allow for evaluating the impact of mesoscale-to-submesoscale variability.

The Future of Oceanography from Space: Introduction to the Special Issue [PDF]

Oceanography, 2010
In this special issue of Oceanography we explore a number of different science drivers for the future of oceanography from space. Given all the developments in remote sensing over the last few decades, this area is rich for inquiry, and we do not presume
