Sablefish, Anoplopoma fimbria, Populations on Gulf of Alaska Seamounts
Sablefish, Anoplopoma fimbria, were tagged and released on Gulf of Alaska seamounts during 1999–2002 to determine the extent, if any, of emigration from the seamounts back to the continental slope and of movement between seamounts.
Seventeen sablefish from Gulf of Alaska seamounts have been recovered on the continental slope since tagging began,
verifying that seamount to slope migration occurs. Forty-two sablefish were recovered on the same seamounts where they were tagged, and none have been recaptured on
seamounts other than the ones where they were released.
Sablefish populations on Gulf of Alaska seamounts are made up of individuals mostly older than 5 years and are maledominant, with sex ratios varying from 4:1 up to 10:1 males to females. Males are smaller than females, but the average age of males is greater than that of females, and males have a greater range of age (4–64 yr) than females (4–48 yr). Otoliths of seamount fish frequently have an area
of highly compressed annuli, known as the transition zone, where growth has suddenly and greatly slowed or even stopped. Because transition zones can be present in both younger and older seamount fish and are rare in slope fish, formation of otolith transition zones may be related to travel to the seamounts.
The route sablefish use to reach the seamounts is so far unknown. One possibility is that fish enter the eastward-flowing North Pacific Current off the Aleutian Islands or
western Gulf of Alaska and travel more or less passively on the current until encountering a seamount. The route from seamount back to slope would likely be the northwardflowing
Alaska Current. These routes are discussed in light of tag recovery locations of slope- and seamount-tagged fish
Late Night at LDs
As I am giving my full attention to the Western omelet, home fries, and rye toast on my plate, I do not notice what is going on around me. I’m not drunk, but I’m not sober either. I’m with some friends I know well and some people I barely know, but they all seem nice enough to share a late night meal. I’m starving.
I start to realize that more and more non-college students enter LDs, presumably local Gettysburg residents. Some are being loud and boisterous, not unlike many of the people sitting at my very own table, and someone offhand says, “fucking locals.” [excerpt
Avalanches, thresholds, and diffusion in meso-scale amorphous plasticity
We present results on a meso-scale model for amorphous matter in athermal,
quasi-static (a-AQS), steady state shear flow. In particular, we perform a
careful analysis of the scaling with the lateral system size, , of: i)
statistics of individual relaxation events in terms of stress relaxation, ,
and individual event mean-squared displacement, , and the subsequent load
increments, , required to initiate the next event; ii) static
properties of the system encoded by , the distance of local
stress values from threshold; and iii) long-time correlations and the emergence
of diffusive behavior. For the event statistics, we find that the distribution
of is similar to, but distinct from, the distribution of . We find a
strong correlation between and for any particular event, with with . completely determines the scaling exponents
for given those for . For the distribution of local thresholds, we
find is analytic at , and has a value which scales with lateral system length as . Extreme value statistics arguments lead to a scaling relation
between the exponents governing and those governing . Finally, we
study the long-time correlations via single-particle tracer statistics. The
value of the diffusion coefficient is completely determined by and the scaling properties of (in particular from
) rather than directly from as one might have naively
guessed. Our results: i) further define the a-AQS universality class, ii)
clarify the relation between avalanches of stress relaxation and diffusive
behavior, iii) clarify the relation between local threshold distributions and
event statistics

My (Not So) Angry Vagina
Why is feminism a dirty word? Why are celebrities from Susan Sarandon to Lady Gaga and Katy Perry explicitly rejecting the feminist label? And why is Carrie Underwood saying, “I wouldn’t go so far as to say I am a feminist, that can come off as a negative connotation.”
Since when was there a negativity surrounding feminism? Well, basically since forever. [excerpt
