Estimating ocean heat content from the ocean thermal expansion parameters using satellite data [PDF]

open access: yesEarth System Dynamics
Ocean heat content (OHC) is a depth-integrated physical oceanographic variable used to precisely measure ocean warming. Because of the limitations associated with in situ conductivity, temperature, and depth (CTD) data as well as ocean reanalysis system ...

Validation protocol for the evaluation of space-borne lidar particulate back-scattering coefficient bbp

open access: yesFrontiers in Remote Sensing, 2023
Introduction: Space-borne lidar measurements from sensors such as CALIOP were recently used to retrieve the particulate back-scattering coefficient, bbp, in the upper ocean layers at a global scale and those observations have a strong potential for the ...

Narrowband shortwave minima of multispectral reflectance as indication of algal blooms associated with the mesoscale variability in the Brazil-Malvinas Confluence

open access: yesOceanologia, 2018
Summary: We examine the narrowband shortwave minima (NSM) of multispectral reflectance as indication of mesoscale algal blooms. They are frequent in the Brazil-Malvinas confluence zone (BMCZ) where our testing site (TS) belongs.

A New Approach of Oil Spill Detection Using Time-Resolved LIF Combined with Parallel Factors Analysis for Laser Remote Sensing

open access: yesSensors, 2016
In hope of developing a method for oil spill detection in laser remote sensing, a series of refined and crude oil samples were investigated using time-resolved fluorescence in conjunction with parallel factors analysis (PARAFAC).

Neural Network Reflectance Prediction Model for Both Open Ocean and Coastal Waters

open access: yesRemote Sensing, 2020
Remote sensing of global ocean color is a valuable tool for understanding the ecology and biogeochemistry of the worlds oceans, and provides critical input to our knowledge of the global carbon cycle and the impacts of climate change.

Are the world's oceans optically different? [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2011
Regional differences in the Sea‐viewing Wide Field‐of‐view Sensor chlorophyll algorithm uncertainty were observed in a large global data set containing coincident in situ measurements of chlorophyll a concentration (Chla) and spectral radiometry. The uncertainty was found to be systematic when the data were sorted by ocean: Atlantic, Pacific, Southern,
