bathymetry image - New research on a field of pockmarks—large, circular depressions on the seafloor—offshore of Central California has revealed that powerful sediment flows, not methane gas eruptions, maintain these prehistoric formations. This work by a team of researchers from MBARI, USGS, and Stanford University provides important information to guide decision-making about responsible use and management of the seafloor off California, including site assessments for the development of offshore wind farms.

schematics - diagram illustrating how the patterns of erosion and deposition associated with three sediment gravity flows could produce the stacked pockmarks and lateral migration observed in AUV-collected Chirp profiles.

map and cross sections - AUV-collected Chirp profiles (a-a’ and b-b’) running the length of the main section of the Sur Pockmark Field annotated with lines tracing the reflective horizons between the two channel systems.

Currently at work on a #poem for a friend whose #pockmarks have hindered her perception of her own beauty for her entire life. She has a thing for stars, thus the poem's title, "Star Tissue"
