Shallow ponds are heterogeneous habitats within a temperate salt marsh ecosystem
(John Wiley & Sons, 2017-06-15)Integrating spatial heterogeneity into assessments of salt marsh biogeochemistry is becoming increasingly important because disturbances that reduce plant productivity and soil drainage may contribute to an expansion of ... -
Constraining the rate of oceanic deoxygenation leading up to a Cretaceous Oceanic Anoxic Event (OAE-2: ~94 Ma)
(American Association for the Advancement of Science, 2017-08-09)The rates of marine deoxygenation leading to Cretaceous Oceanic Anoxic Events are poorly recognized and constrained. If increases in primary productivity are the primary driver of these episodes, progressive oxygen loss ... -
Stable isotope analyses of feather amino acids identify penguin migration strategies at ocean basin scales
(2017-07)Identifying the at-sea distribution of wide ranging 20 marine predators is critical to understanding their ecology. Advances in electronic tracking devices and intrinsic biogeochemical markers have greatly improved our ... -
Toward establishing model organisms for marine protists : Successful transfection protocols for Parabodo caudatus (Kinetoplastida: Excavata)
(2017-06)We developed protocols for, and demonstrated successful transfection of, the free-living kinetoplastid flagellate Parabodo caudatus with three plasmids carrying a fluorescence reporter gene (pEF-GFP with the EF1 alpha ... -
Mining mass spectrometry data : using new computational tools to find novel organic compounds in complex environmental mixtures
(2017-05)Untargeted metabolomics datasets provide ample opportunity for discovery of novel metabolites. The major challenge is focusing data analysis on a short list of metabolites. Here, we apply a combination of computational ... -
Relationship between water and aragonite barium concentrations in aquaria reared juvenile corals
(Elsevier, 2017-04-09)Coral barium to calcium (Ba/Ca) ratios have been used to reconstruct records of upwelling, river and groundwater discharge, and sediment and dust input to the coastal ocean. However, this proxy has not yet been explicitly ... -
Controllability, not chaos, key criterion for ocean state estimation
(Copernicus Publications on behalf of the European Geosciences Union & the American Geophysical Union, 2017-07-19)The Lagrange multiplier method for combining observations and models (i.e., the adjoint method or "4D-VAR") has been avoided or approximated when the numerical model is highly nonlinear or chaotic. This approach has been ... -
Constraints on melt content of off-axis magma lenses at the East Pacific Rise from analysis of 3-D seismic amplitude variation with angle of incidence
(John Wiley & Sons, 2017-06-28)We use 3-D multichannel seismic data to form partial angle P wave stacks and apply amplitude variation with angle (AVA) crossplotting to assess melt content and melt distribution within two large midcrustal off-axis magma ... -
Extraction of uranium from seawater : design and testing of a symbiotic system
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-06)Seawater is estimated to contain 4.5 billion tonnes of uranium, approximately 1000 times that available in conventional terrestrial resources. Finding a sustainable way to harvest uranium from seawater will provide a ... -
High-frequency internal waves and thick bottom mixed layers observed by gliders in the Gulf Stream
(John Wiley & Sons, 2017-06-26)Autonomous underwater gliders are conducting high-resolution surveys within the Gulf Stream along the U.S. East Coast. Glider surveys reveal two mechanisms by which energy is extracted from the Gulf Stream as it flows over ... -
Calibration of the carbon isotope composition (δ13C) of benthic foraminifera
(John Wiley & Sons, 2017-06-03)The carbon isotope composition (δ13C) of seawater provides valuable insight on ocean circulation, air-sea exchange, the biological pump, and the global carbon cycle and is reflected by the δ13C of foraminifera tests. Here ... -
Deep convection simulation from the MITgcm (MIT General Circulation Model) (IVOMLS project)
(Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2017-08-07)All experiments are preformed using the MIT General Circulation Model (MITgcm). The model is configured to allow non-hydrostatic dynamics to explicitly resolve deep convection. The model domain is a box with periodic ... -
Habitat preferences of baleen whales in a mid-latitude habitat
(2016-08)Understanding the dynamics of baleen whale distribution is essential to predict how environmental changes can affect their ecology and, in turn, ecosystem functioning. Recent work showed that mid-latitude habitats along ... -
Quantifying bamboo coral growth rate nonlinearity with the radiocarbon bomb spike : a new model for paleoceanographic chronology development
(2017-04)Bamboo corals, long-lived cold water gorgonin octocorals, offer unique paleoceanographic archives of the intermediate ocean. These Isididae corals are characterized by alternating gorgonin nodes and high Mg-calcite internodes, ... -
Convection driven by temperature and composition flux with the same diffusivity
(2017-05)Temperature, pressure, and composition determine density of fluids within the earth, the ocean, our atmosphere, stars and planets. In some cases, variation of composition component C competes equally with temperature T to ... -
Underwater ambient noise in a baleen whale migratory habitat off the Azores
(Frontiers Media, 2017-04-25)Assessment of underwater noise is of particular interest given the increase in noise-generating human activities and the potential negative effects on marine mammals which depend on sound for many vital processes. The ... -
A review of protist grazing below the photic zone emphasizing studies of oxygen-depleted water columns and recent applications of in situ approaches
(Frontiers Media, 2017-04-26)Little is still known of the impacts of protist grazing on bacterioplankton communities in the dark ocean. Furthermore, the accuracy of assessments of in situ microbial activities, including protist grazing, can be affected ... -
“Climate response functions” for the Arctic Ocean : a proposed coordinated modelling experiment
(Copernicus Publications on behalf of the European Geosciences Union, 2017-07-21)A coordinated set of Arctic modelling experiments, which explore how the Arctic responds to changes in external forcing, is proposed. Our goal is to compute and compare "climate response functions" (CRFs) – the transient ... -
An oceanic ultra-violet catastrophe, wave-particle duality and a strongly nonlinear concept for geophysical turbulence
(MDPI AG, 2017-06-29)There is no theoretical underpinning that successfully explains how turbulent mixing is fed by wave breaking associated with nonlinear wave-wave interactions in the background oceanic internal wavefield. We address this ... -
Winter-to-summer transition of Arctic sea ice breakup and floe size distribution in the Beaufort Sea
(University of California Press, 2017-07-26)Breakup of the near-continuous winter sea ice into discrete summer ice floes is an important transition that dictates the evolution and fate of the marginal ice zone (MIZ) of the Arctic Ocean. During the winter of 2014, ...
