Scientists in the G&G Department seek knowledge of the structure, composition, and dynamics of the earth’s interior, the origin and evolution of the earth’s crust, controls on ocean and climate change on time scales of decades to 100 million years, and processes of mass and energy transfer at the land-sea interface.

Geochemistry of fluids from Earth’s deepest ridge-crest hot-springs : Piccard hydrothermal field, Mid-Cayman Rise
(Elsevier, 2018-02-13)Hosted in basaltic substrate on the ultra-slow spreading Mid-Cayman Rise, the Piccard hydrothermal field is the deepest currently known seafloor hot-spring (4957–4987 m). Due to its great depth, the Piccard site is an ... -
Microearthquake activity on the Orozco Fracture Zone : preliminary results from Project ROSE
(Woods Hole Oceanographic Institution, 1981-09)We present preliminary hypocenter determinations for 52 earthquakes recorded by a large multiinstitutional network of ocean bottom seismometers and ocean bottom hydrophones in the Orozco Fracture Zone in the eastern ... -
Viscous demagnetization and the longevity of paleomagnetic polarity messages
(Woods Hole Oceanographic Institution, 1981-06)Viscous decay of magnetic polarity messages in rocks is slowed 3- to-6 fold by the reversing nature of the geomagnetic field, compared with the effect expected in a field that is constantly polarized oppositely to the ... -
Acoustic environment of the Hatteras and Nares Abyssal Plains, western North Atlantic Ocean, determined from velocities and physical properties of sediment cores
(Woods Hole Oceanographic Institution, 1981-06)Seventeen piston cores up to 13 m long were recovered from representative acoustic and lithologic environments of the Hatteras and Nares Abyssal Plains in the western North Atlantic. Compressional-wave velocities (corrected ... -
A synthesis of deglacial deep‐sea radiocarbon records and their (in)consistency with modern ocean ventilation
(John Wiley & Sons, 2018-01-08)We present a synthesis of 1,361 deep‐sea radiocarbon data spanning the past 40 kyr and computed (for 14C‐dated records) from the same calibration to atmospheric 14C. The most notable feature in our compilation is a long‐term ... -
Field evaluation of Sea Data directional wave gage : (Model 635-9)
(Woods Hole Oceanographic Institution, 1981-05)A directional wave gage consisting of a two-axis electromagnetic current meter and a pressure sensor, developed by Sea Data Corporation, with modifications specified by the author, was successfully deployed during the ... -
Local seismicity of the Rainbow massif on the Mid‐Atlantic Ridge
(John Wiley & Sons, 2018-01-20)The Rainbow massif, an oceanic core complex located in a nontransform discontinuity on the Mid‐Atlantic Ridge (36°N), is notable for hosting high‐temperature hydrothermal discharge through ultramafic rocks. Here we report ... -
The geographic variation of midwater sound-scattering(u)
(Woods Hole Oceanographic Institution, 1966-03)It is suggested in this report that the intensity of midwater sound-scattering in the ocean varies from point to point as the abundance of marine life varies. Several charts depicting variations in the abundance of marine ... -
Carbon and mineral transformations in seafloor serpentinization systems
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2018-02)This thesis examines abiotic processes controlling the transformation and distribution of carbon compounds in seafloor hydrothermal systems hosted in ultramafic rock. These processes have a direct impact on carbon budgets ... -
Low and variable ecosystem calcification in a coral reef lagoon under natural acidification
(John Wiley & Sons, 2017-10-09)Laboratory‐based CO2 experiments and studies of naturally low pH coral reef ecosystems reveal negative impacts of ocean acidification on the calcifying communities that build coral reefs. Conversely, in Palau's low pH ... -
Radiocarbon content of dissolved organic carbon in the South Indian Ocean
(John Wiley & Sons, 2018-01-24)We report four profiles of the radiocarbon content of dissolved organic carbon (DOC) spanning the South Indian Ocean (SIO), ranging from the Polar Front (56°S) to the subtropics (29°S). Surface waters held mean DOC Δ14C ... -
Oceanographic significance of Pacific late Miocene clacareous nannoplankton
(Woods Hole Oceanographic Institution, 1980-12)An analysis of the variability in the composition and distribution of Pgcific Late Miocene calcareous nannoplankton about their average biogeography shows that there are primarily two environmental factors causing that ... -
The crustal structure of the Kane fracture zone from seismic refraction studies
(Woods Hole Oceanographic Institution, 1980-12)A detailed seismic refraction experiment was carried out across the Kane Fracture Zone near 24°N, 44°W using explosive and air gun sound sources and eight ocean bottom hydrophone receivers. The shooting lines and receive ... -
Reconstructing Northeastern United States temperatures using Atlantic white cedar tree rings
(IOP Publishing, 2017-11-02)Our knowledge of climate variability in the densely populated Northeastern United States is limited to instrumental data of the last century. Most regional paleoclimate proxies reflect a mix of climate responses, which ... -
Thermal conductivity measurement of fused silica glass
(Woods Hole Oceanographic Institution, 1980-08)The reproducibility of thermal conductivity measurements on fused silica glass by various investigators using different techniques suggests its suitability as a standard for such measurements. Our laboratory measurements ... -

(Woods Hole Oceanographic Institution, 1980-07)A meeting was held March 11-15, 1980 to develop and refine the hierarchy of problems to be addressed by the high energy benthic boundary layer experiment. This document outlines revised program goals and the critical ... -
Malaysia Airlines flight MH370 search data reveal geomorphology and seafloor processes in the remote southeast Indian Ocean
(Elsevier, 2017-11-08)A high-resolution multibeam echosounder (MBES) dataset covering over 279,000 km2 was acquired in the southeastern Indian Ocean to assist the search for Malaysia Airlines Flight 370 (MH370) that disappeared on 8 March 2014. ... -
