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...
A simple theory is presented for steady geostrophic circulation of a stratified fluid in a rectangular basin with a circumpolar connection. The interior flow obeys the β-plane Sverdrup vorticity balance, and the circulation is closed by geostrophic boundary currents. The circulation is forced by surface thermal gradients and wind-driven Ekman...

We report that the submerged microbubbles are an efficient source of diffuse radiance and may contribute to a rapid transition to the diffuse asymptotic regime. In this asymptotic regime an average cosine is easily predictable and measurable.
We tested closure between in situ radiometric and absorption coefficient measurements by using a nearly backscattering-independent remote-sensing reflectance model that employs the remote-sensing reflectance at three wavelengths. We show that only a small error is introduced into the closure model when the proper functional relationships of f/Q and the backscattering...
The redox dye 5-cyano-2, 3-ditolyl tetrazolium chloride (CTC) is used in aquatic sciences as a vital stain for enumeration of respiring bacteria in situ. Questions concerning its efficacy have been raised. We propose that the abundance of CTC-positive (CTC+) bacteria is a useful parameter in microbial ecology based on the...
The majority of bacteria suspended in seawater do not appear to be metabolically active or in good physiological condition as assessed by various methods. We tested the idea that a large fraction of ‘inactive’ bacterial cells can become ‘active’ with respect to detectable cell-specific electron transport system (ETS) activity, determined...
A mesoscale atmospheric model is used to address the characteristics of stratified flow bounded by a side
wall along a varying coastline. Initial Froude number values are varied through alteration of marine inversion
strength, permitting examination of supercritical, subcritical, and transcritical flow regimes encountering several
coastal configurations. Consistent with shallow...
The diffusivity dependence of internal boundary layers in solutions of the continuously stratified, diffusive
thermocline equations is revisited. If a solution exists that approaches a two-layer solution of the ideal thermocline
equations in the limit of small vertical diffusivity kᵥ, it must contain an internal boundary layer that collapses
to...
During SHEBA, thin ice and freshening of the Arctic Ocean surface in the Beafort Sea led to speculation that perennial sea ice was disappearing [McPhee et al., 1998]. Since 1987, we have collected salinity, δ¹⁸O and Ba profiles near the initial SHEBA site and, in 1997, we ran a section...
Root disease fungi attack and destroy the tree’s root system, resulting in growth loss, decay, death, or wind throw of infected trees. Trees with root disease also are more susceptible to pests, especially bark beetles. On the other hand, root diseases are a component of the forest ecosystem and play...
