Imaging marine geophysical environments with vector acoustics [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2006
Using vector acoustic sensors for marine geoacoustic surveys instead of the usual scalar hydrophones enables one to acquire three-dimensional (3D) survey data with instrumentation and logistics similar to current 2D surveys. Vector acoustic sensors measure the sound wave direction directly without the cumbersome arrays that hydrophones require.

Combatting the data crisis: a primer on using artificial intelligence in marine biodiversity

open access: yesFrontiers in Marine Science
Accelerated biodiversity loss due to anthropogenic factors has led some researchers to suggest Earth may be approaching a 6th mass extinction event. While artificial intelligence (AI) cannot counteract this biodiversity loss directly, AI has seen an ...

Marine gravity image available

open access: yesEos, Transactions American Geophysical Union, 1994
The image below shows the gravity field from 30–72°S computed from Geosat geodetic mission (GM) and exact repeat mission (ERM) data. A color shaded‐relief image of these gravity anomalies is available from NOAA in poster form (report MGG‐8, [Marks et al., 1993] and also as a digital gridded data set on CD‐ROM. To order, contact the National Geophysical
