Pew Marine Fellowship

I am honored and thrilled to share the news that I have been selected to join the 2020 class of Pew Marine Fellows. I'm looking forward to using this tremendous opportunity to help as many people as possible exploit the full potential of underwater landscape mosaics for coral reef restoration. Read more...

Time series of mosaics

Mosaics are excellent tools for monitoring an area over time. They can capture changes at both large and small scales simultaneously. I recently updated a page with several example applications demonstrating the utility of time series of mosaics. Read more...

14.5 Gigapixel mosaic

I have a new result from our large area survey at the Flower Garden Banks National Marine Sanctuary in Jun 2019. We mapped an area of over 100 x 100 m and have been able to render that in a single 2.5-D point cloud as well as a 2-D orthomosaic. This is the largest single mosaic our group has created to date: 14.5 Gigapixels! Read more...

Large-area mosaics

Our team has been steadily working towards increasing the area that can be mosaicked at high resolution. This page summarizes results over the years, giving an indication of the progress and current limits of the technology. Read more...

Correlation between observed and modeled polarized upwelling DLOP

Polarized upwelling BRDF

Models for the unpolarized BRDF have been validated, but variations in the polarization of the upwelling radiance due to the sun angle, viewing geometry, dissolved material, and suspended particles have not been systematically documented. In this work, we simulated the upwelling radiance distribution using a Monte Carlo-based radiative transfer code and measured it using a set of fish-eye cameras with linear polarizing filters.
