Ocean (De)oxygenation Across the Last Deglaciation:Insights for the Future
Ocean (De)oxygenation Last Deglaciation Insights for the Future
2015/7/17
Anthropogenic warming is expected to drive oxygen out of the ocean as the water temperature rises and the rate of exchange between subsurface waters and the atmosphere slows due to enhanced upper ocea...
Endeavour Segment of the Juan de Fuca Ridge:One of the Most Remarkable Places on Earth

2015/7/14
Low-temperature (typically 5–75°C) fluid, commonly referred to as "diffuse" hydrothermal flow, emanates from fractures over a significant portion of the Juan de Fuca Ridge seafloor in the Northeast Pa...
Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets
Estimating Zooplankton Biomass Water Column Near Endeavour Segment Juan de Fuca Ridge Acoustic Backscatter Concurrently Towed Nets
2015/7/14
Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate...
Dom João de Castro is an isolated seamount located in the Azores archipelago (Northeast Atlantic), between the islands Terceira and São Miguel. The shallower parts of this seamount were form...
Variability of Pseudo-nitzschia and domoic acid in the Juan de Fuca eddy region and its adjacent shelves
Pseudo-nitzschia and domoic acid adjacent shelves
2014/4/17
The Juan de Fuca eddy is a toxic ‘‘hot spot.’’ Domoic acid (DA) was detected in the eddy during each of six
cruises over a 4-yr study, although Pseudo-nitzschia abundance and toxin concentrations wer...

Seawater movements are of three kinds: currents, waves, and tides. Observations were made five times a day for three and one-quarter months in the Strait of Cassis. Mariners' reports of a westward cur...
The Probability Distribution of the Thorpe Displacement within Overturns in Juan de Fuca Strait
Probability Distribution of the Thorpe Displacement Overturns Juan de Fuca Strait
2008/6/4
Vertical mixing in the ocean can sometimes be quantified by measurements of the Thorpe overturning scale, LT. In regions of weak mixing and weak density gradients such measurements may be limited by s...
Long-term changes in the areal hypolimnetic oxygen deficit (AHOD) of Onondaga Lake: Evidence of sediment feedback
Long-term changes areal hypolimnetic oxygen
2014/4/30
Long-term trends in the rate of depletion of hypolimnetic dissolved oxygen (DO) are documented for ionically
enriched hypereutrophic Onondaga Lake, New York, for the 1978–2002 interval. Depletion rat...

We conducted a diurnal study of gradients of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP), dimethylsulfoxide (DMSO), and bacterial numbers in a stratified coastal salt pond (Sa...
A role for manganese in superoxide dismutases and growth of iron-deficient diatoms
superoxide dismutases iron-defi cient diatoms
2014/5/19
We have discovered that coastal and oceanic diatoms require more manganese (Mn) to grow in iron (Fe) -deficient
than in Fe-sufficient seawater. At low inorganic concentrations, like those...
