Ocean PHILLS hyperspectral imager: design, characterization, and calibration

TL;DR: The Ocean Portable Hyperspectral Imager for Low-Light Spectroscopy (Ocean PHILLS) is a hyperspectral imager specifically designed for imaging the coastal ocean that uses a thinned, backsideilluminated CCD for high sensitivity and an all-reflective spectrograph with a convex grating in an Offner configuration to produce a nearly distortionfree image.
Journal ArticleDOI

Near-surface ocean velocity from infrared images: Global Optimal Solution to an inverse model

TL;DR: In this paper, the authors proposed a global optimal solution (GOS) method to obtain ocean surface velocities from sequences of thermal (AVHRR) space-borne images by inverting the heat conservation equation.
Journal ArticleDOI

Nonlinear inverse model for velocity estimation from an image sequence

TL;DR: In this paper, a nonlinear model has been created for estimating motion field under the constraint of conservation of intensity, and an algorithm with progressive relaxation of the overconstraint to improve the performance of the velocity estimation is also proposed.

Submesoscale tidal eddies in the wake of coral islands and reefs: satellite data and numerical modelling

TL;DR: In this paper, a detailed view of the sub-mesoscale variability in a part of the Great Barrier Reef lagoon, Australia, that includes a number of small islands was obtained by using a "stereo" pair of 2-m-resolution visible-band images that were acquired just 54 s apart by the WorldView-3 satellite near-surface current and vorticity were extracted at a 50m resolution from those data using a cross-correlation technique and an optical flow method, each yielding a similar result.
