Journal ArticleDOI
The foraging strategy of a subtidal and deep-sea deposit feeder1
TL;DR: These observations indicate that this sedentary animal's food supply depends predominantly on the rate of sedimentation into the pit that is produced via its feeding and defecating activities, rather than on the rates of microbial regeneration or production that goes on within.
Journal ArticleDOI
The effects of bacteria on the flow behavior of clay-seawater suspensions
TL;DR: The presence of glue-like exopolymer produced by the marine benthic bacterium Alteromonas atlantica present in concentrations comparable with typical marine muds can enhance the yield stress of dilute clay-seawater suspensions typical of the sediment-water interface by 60%.
Journal ArticleDOI
In situ tensile fracture toughness of surficial cohesive marine sediments
TL;DR: In this paper, the first in situ measurements of tensile fracture toughness of soft, surficial, cohesive marine sediments are reported, which are in agreement with standard laboratory methods of K IC measurements in both potter's clay and natural sediments.
Journal ArticleDOI
Gut-marker and gut-fullness methods for estimating field and laboratory effects of sediment transport on ingestion rates of deposit-feeders'
TL;DR: Gut fullness in continous feeders may provide more information on recent change in feeding rate than on feeding rate itself, suggesting that gut fullness may provide a tracer-free method of gaining some kinetic information on continuously feeding animals.
Journal ArticleDOI
Acoustic remote sensing of benthic activity: A statistical approach
TL;DR: In this article, acoustic backscatter at 40 kHz was recorded from a circular area of silt 75 m in radius every 0.1 d at a water depth of 91 m off the coast of northern California for 49 d in winter 1988-1989.
