Climate variation, carbon flux, and bioturbation in the abyssal North Pacific
No full textWe hypothesized that seasonal and interannual climate-mediated changes in particulate organic carbon (POC)
flux would affect bioturbation and ultimately the sequestration of organic carbon in the deep sea. An 18-yr timeseries
photographic record from 4100-m depth in the northeast Pacific Ocean showed increased abundance of
Echinocrepis rostrata, a common epibenthic echinoid and bioturbator, since the late 1990s. Abundance, size, and
speed data were used to estimate bioturbation potential to track long-term changes in the volume of sediment
disturbed by E. rostrata. There was no secular increase in E. rostrata bioturbation over 18 yr despite increased
population size, although periodic variations in bioturbation were significantly correlated with POC flux.
Expected changes in POC flux and bioturbation rates due to climate variation could lead to altered rates of
carbon sequestration in deep-sea sediments, affecting the global carbon cycle

The Role of Carrion Supply in the Abundance of Deep-Water Fish off California
No full textFew time series of deep-sea systems exist from which the factors affecting abyssal fish populations can be evaluated. Previous analysis showed an increase in grenadier abundance, in the eastern North Pacific, which lagged epibenthic megafaunal abundance, mostly echinoderms, by 9–20 months. Subsequent diet studies suggested that carrion is the grenadier's most important food. Our goal was to evaluate if changes in carrion supply might drive the temporal changes in grenadier abundance. We analyzed a unique 17 year time series of abyssal grenadier abundance and size, collected at Station M (4100 m, 220 km offshore of Pt. Conception, California), and reaffirmed the increase in abundance and also showed an increase in mean size resulting in a ~6 fold change in grenadier biomass. We compared this data with abundance estimates for surface living nekton (pacific hake and jack mackerel) eaten by the grenadiers as carrion. A significant positive correlation between Pacific hake (but not jack mackerel) and grenadiers was found. Hake seasonally migrate to the waters offshore of California to spawn. They are the most abundant nekton species in the region and the target of the largest commercial fishery off the west coast. The correlation to grenadier abundance was strongest when using hake abundance metrics from the area within 100 nmi of Station M. No significant correlation between grenadier abundance and hake biomass for the entire California current region was found. Given the results and grenadier longevity, migration is likely responsible for the results and the location of hake spawning probably is more important than the size of the spawning stock in understanding the dynamics of abyssal grenadier populations. Our results suggest that some abyssal fishes' population dynamics are controlled by the flux of large particles of carrion. Climate and fishing pressures affecting epipelagic fish stocks could readily modulate deep-sea fish dynamics
ADAM SMITH'S OPTIMISTIC TELEOLOGICAL VIEW OF HISTORY
No full textAdam Smith's four-stage theory provides the framework for his writings on history. The fourth stage is the commercial epoch; the culmination of history in this stage is a key component in the conventional interpretation of Adam Smith as a prophet of commercialism. In two historical case studies Smith shows the capacity of commercial society to regenerate itself. This potent capacity suggests that commercial society is inevitable. At a certain point in time it also overcomes the major obstacles to its permanence. Smith's philosophy of history anticipates the end of history views of Kant and Hegel.Political Economy,
A new deep-sea species of epibenthic acorn worm (Hemichordata, Enteropneusta)
No full textIndividuals of an enteropneust, Tergivelum baldwinae n. gen., n. sp. were videotaped at a depth of about 4 km in the eastern Pacific and collected by a remotely operated vehicle. The living worms range in length from 9 to 28 cm and are dark brown anteriorly and beige posteriorly. The proboscis is shaped like a shallow dome, indented on either side by a laterodorsal fossa housing a prominent proboscis nerve. The collar comprises a thin transverse crest dorsally and two laterally projecting lips on either side of the mouth ventrally. The mouth is oriented parallel to the substratum and is flanked by large left and right buccal muscles (contrasting with the rudimentary musculature elsewhere in the body). The respiratory pharynx of the trunk extends far anteriorly so that much of it lies dorsal to the mouth opening. The gill bars are not joined by synapticles. The laterodorsal body wall at the anterior extremity of the trunk
extends as two conspicuous flaps (back veils) that run posteriorly as unattached coverings over the anterior 30-50% of the trunk. On either side of the midline, the body wall of the trunk is extended as a narrow lateroventral fold. Within the trunk runs the intestine, which lacks hepatic sacculations and opens at an
anus at the posterior end of the body. Frame analysis of videotapes suggests that the worm can secrete a mass of mucus around the body to facilitate demersal drifting from one epibenthic foraging site to the next. We include a preliminary phylogenetic analysis based on rDNA sequences from T. baldwinae n. gen., n. sp. and additional deep-sea enteropneusts not yet formally described taxonomically (sequence data place them unexpectedly close to ptychoderids). Until more is known about the group as a whole, it is prudent to leave family level classification of T. baldwinae n. gen., n. sp. as incertae sedis

Size–frequency dynamics of NE Pacific abyssal ophiuroids (Echinodermata: Ophiuroidea)
No full textThe 17-year time-series study at Station M in the NE Pacific has provided one of the longest datasets on deep-sea ophiuroids to date. Station M is an abyssal site characterized by low topographical relief and seasonal and interannual variation in surface-derived food inputs. From 1989 to 2005, over 31,000 ophiuroid specimens were collected. Size–frequency distributions of the four dominant species, Ophiura bathybia, Amphilepis patens, Amphiura carchara and Ophiacantha cosmica, were examined for recruitment and the role of surface-derived food supplies on body size distributions. Juveniles were collected in sediment traps and used to investigate settlement patterns and seasonality. Trawl samples showed no indication of seasonal changes in recruitment to larger size classes; however, there was evidence of seasonal settling of juveniles. Interannual differences in median disk diameters and size distributions of trawl-collected adults are greater than those at the seasonal scale. Three of the four species, O. bathybia, A. patens and O. cosmica, had co-varying monthly median disk diameters, suggesting they may have a similar factor(s) controlling their growth and abundance. Interannual differences in monthly size distributions were generally greater than those between seasons. Cross-correlations between the particulate organic carbon (POC) flux (food supply) and size distribution indices for O. bathybia, A. patens and O. cosmica all were significant indicating that increases in food supply were followed by increases in the proportion of smaller size classes after approximately 17–22 months. These findings suggest that food inputs are indeed an important factor influencing deep-sea ophiuroid populations on interannual time scales, more generally supporting the long-hypothesized connection between food availability and population size structure in the deep sea
