This study shows how patronage framed and fashioned the careers of Thomas Hobbes and
his patron William Cavendish, the earl of Newcastle. Newcastle's protection allowed
Hobbes to articulate heterodox ideas without immediate fear of reprisal. It also enabled
him to solidify his status as a gentleman and the intellectual equal...
Hydrographic and velocity profiles were made through a small baroclinic cyclonic eddy during the Arctic Internal Wave Experiment in the Canada Basin in April 1985. The maximum measured azimuthal velocity was 0.38 m s⁻¹ at a depth of 115 m, with velocities decaying to near zero at 30 and 270...
The upwelling-driven coastal jet off Oregon is in geostrophic balance to first order.
The accompanying thermal wind shear is stable to shear instability. Yet enhanced
turbulence is observed in the upwelling jet, typically as long, thin patches with horizontal
to vertical aspect ratios of 10² to 10³ (median value ~300)....
Milk contains elements of numerous proteolytic systems (zymogens, active proteases, protease inhibitors and protease activators) produced in part from blood, in part by mammary epithelial cells and in part by immune cell secretion. Researchers have examined milk proteases for decades, as they can cause major defects in milk quality and...
National-scale analyses of fire occurrence are needed to prioritize fire policy and
management activities across the United States. However, the drivers of national-scale
patterns of fire occurrence are not well understood, and how the relative importance of human
or biophysical factors varies across the country is unclear. Our research goal...
We examine the 0–100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329. We use multivariate statistical analyses (Q-mode factor analysis...
Horizontal current measurements from an array of moored acoustic Doppler profilers are assimilated sequentially into a model of coastal wind-driven circulation off Oregon during the upwelling season of May–August 2001. Model results are compared against independent moored and ship survey data to document a positive effect of velocity data assimilation...
From mid-May to August 2011, extreme runoff in the Columbia River ranged from 14,000 to over 17,000 m³/s, more than two standard deviations above the mean for this period. The extreme runoff was the direct result of both melting of anomalously high snowpack and rainfall associated with the 2010–2011 La Niña....
Surface tides are the heartbeat of the ocean. Because they are controlled by Earth's motion relative to other astronomical objects in our solar system, surface tides act like clockwork and generate highly deterministic ebb and flow familiar to all mariners. In contrast, baroclinic motions at tidal frequencies are much more...
Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and explicitly represented in modern eddy-resolving numerical models of global ocean circulation. The same cannot be said for...
