Sound Cut, Record Number 62026003
(Woods Hole Oceanographic Institution, 1994-08-09)
Recording of 2+ beluga whales made by WHOI Rowboat recorder; Atlantic Research LC34 hydrophone. Jaw claps; pulsed clicks; squeals.
Sound Cut, Record Number 67028001
(Woods Hole Oceanographic Institution, 1992-05-04)
Recording of 2 Ribbon seals. One downsweep and an in-air growl recorded underwater through the ice.
Biological-physical interactions on Georges Bank : plankton transport and population dynamics of the ocean quahog, Arctica islandica
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-06)
Advective losses of bank water during winter because of strong wind forcing were hypothesized to be a significant factor limiting recruitment of Georges Bank cormnunities. This hypothesis was examined using biological-physical ...
Late Quaternary variability of sedimentary nitrogen isotopes in the eastern South Pacific Ocean
(American Geophysical Union, 2007-05-01)
We present high-resolution bulk sedimentary δ 15N data from the southern edge of the present-day oxygen minimum zone of the eastern South Pacific. The record is interpreted as representing changes in water column nitrogen ...
Higher-order acoustic diffraction by edges of finite thickness
(Acoustical Society of America, 2007-12)
A cw solution of acoustic diffraction by a three-sided semi-infinite barrier or a double edge, where the width of the midplanar segment is finite and cannot be ignored, involving all orders of diffraction is presented. The ...
Stochastic flood and precipitation regimes and the population dynamics of a threatened floodplain plant
(Ecological Society of America, 2005-06)
Boltonia decurrens is an endangered plant restricted to the Illinois River Valley. Its complex life cycle has evolved in response to the dynamics of the historic flood regime, which has changed dramatically in the last ...
Wave evolution across the Louisiana shelf
Observations and third-generation wave model hindcasts of ocean surface gravity waves propagating across the Louisiana shelf show that the effects of the mud environment on wave evolution are complex and episodic. Whereas ...
Stochasticity, heterogeneity, and variance in longevity in human populations
Inter-individual variance in longevity (or any other demographic outcome) may arise from heterogeneity or from individual stochasticity. Heterogeneity refers to differences among individuals in the demographic rates ...
The spatial and temporal abundance patterns of chaetognaths in the western North Atlantic Ocean
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-08)
Zooplankton samples were collected with the MOCNESS (Multiple Opening/ Closing Net and Environmental Sensing System) on six cruises in the western North Atlantic Ocean during the period from August 1975 to November 1977 ...
Sub-tropical seagrass ecosystem metabolism measured by eddy covariance
The metabolism of seagrass ecosystems was examined at 4 sites in south Florida, USA, using the eddy covariance technique under in situ conditions. Three sites were located across a phosphorus-driven productivity gradient ...
