The scheduled February 1985 launch of a radar altimeter aboard the U.S. Navy satellite Geosat has
motivated an in-depth investigation of wind speed retrieval from satellite altimeters. The accuracy of sea
surface wind speed estimated by the Seasat altimeter is examined by comparison with wind speed
estimated by the Seasat...
Moored observations are used to investigate the seasonal change in vertical structure of the cross-shelf
circulation at a midshelf location in the northern California Current System. A streamwise–normal coordinate
system is employed to eliminate meander- and eddy-induced biases in the cross-shelf flow that are unaccounted
for with an alternative, commonly...
We summarize 121 ¹⁴C and in-situ cosmogenic (¹⁰Be and ³⁶Cl) ages that constrain fluctuations of the Irish Ice Sheet (IIS) since the Last Glacial Maximum (LGM) that can be linked to abrupt climate changes in the North Atlantic region. These data provide a robust means to date ice-sheet fluctuations because...
A high-resolution primitive equation model simulation is used to form an energy budget for the principal semidiurnal tide (M₂) over a region of the Hawaiian Ridge from Niihau to Maui. This region includes the Kaena Ridge, one of the three main internal tide generation sites along the Hawaiian Ridge and...
Ocean Drilling Program (ODP) Leg 202 has opened a new window
into understanding late Paleogene and Neogene global environmental
change by providing high-quality sediment sequences from a previously
unsampled region, the eastern South Pacific. Eleven sites (1232–
1242) that record variations on timescales ranging from decades to tens
of millions...
Large rivers represent gateways for the transport of
terrigenous and anthropogenic material to the coastal ocean.
Here we document a ∼700 km2 recirculation or bulge associated
with the Columbia River plume that retains recently discharged
river water sufficiently to create a regional bioreactor.
Fueled by a fluvial nitrate source, this...
Significant attention has been given to how artificial intelligence (AI) can be utilized by society and in scientific fields in recent years. This article explores how AI tools utilized in various fields have been and can be applied to ecological restoration projects, their affiliated benefits and drawbacks, and what those...
We compared canopy arthropod assemblages among overstory conifer and understory angiosperm
species at Teakettle Experimental Forest in the Sierra Nevada in California during 1998–2000. Arthropods were
sampled from upper, middle, and lower crown levels of one overstory tree of each of the four dominant conifer
species (Jeffrey pine, sugar pine,...
River Influences on Shelf Ecosystems (RISE) is the first comprehensive
interdisciplinary study of the rates and dynamics governing the mixing of river and coastal
waters in an eastern boundary current system, as well as the effects of the resultant plume
on phytoplankton standing stocks, growth and grazing rates, and community...
Tidal mixing over a slope was explored using moored time series observations on Kaena Ridge extending northwest from Oahu, Hawaii, during the Survey component of the Hawaii Ocean Mixing Experiment (HOME). A mooring was instrumented to sample the velocity and density field of the lower 500 m of the water...
