Pulsed delivery of subthermocline water to Conch Reef (Florida Keys) by internal tidal bores
Internal tidal bores generated by breaking internal waves cause dramatic, high-frequency variation in temperature, salinity, water velocities, and concentration of chlorophyll a on Conch Reef,Expand
Breaking internal waves on a Florida (USA) coral reef: a plankton pump at work?
TLDR
Internal tidal bores appear to be a predictable, periodic source of cross-shelf transport to Florida coral reefs and an important influence on the spatial and temporal heterogeneity of suspended food particles and larval delivery to the benthos. Expand
Settlement and transport of benthic invertebrates in an intermittent upwelling region
TLDR
Crab settlement was significantly correlated with the rate of temperature increase, corresponding to relaxation events, and sea urchins settled primarily during an unusual relaxation event which possibly involved remote forcing. Expand
Meroplanktonic distribution and circulation in a coastal retention zone of the northern California upwelling system
Previous studies have shown that settlement of several crab species along the coast north of Point Reyes (38°00'N, 123°00'W) occurs primarily during relaxation from upwelling, when warm water flowsExpand
Calorific content of New Zealand marine macrophytes
TLDR
Factors affecting variation in calorific content between species and during the year are discussed, and the application of the current findings to ecological and aquacultural research on New Zealand seaweeds are considered. Expand
Harvest Refugia in Marine Invertebrate Fisheries: Models and Applications to the Red Sea Urchin, Strongylocentrotus franciscanus
TLDR
Hydrodynamic considerations and experimental evidence suggest that species broadcasting gametes suffer greatly reduced fertilization efficiencies as densities decline, and multiple reserves, spaced more closely than the average larval dispersal distance, appear to be an effective and conservative strategy for maintaining healthy populations and sustainable levels of harvest.

Prehistoric fisheries in the Caribbean
Abstract. We studied faunal remains from archaeological sites on five Caribbean islands, each with an early (1,850–1,280 years B.P.) and late (1,415–560 years B.P.) occupation. On each of theseExpand
Effects of hydrographic barriers on population genetic structure of the sea star Coscinasterias muricata (Echinodermata, Asteroidea) in the New Zealand fiords
TLDR
New Zealand's 14 deep‐water fiords possess persistent salinity stratification and mean estuarine circulation that may serve to isolate populations of marine organisms that have a dispersal larval phase, and the pattern of population genetic structure among the fiords suggests a secondary contact between a northern population and a southern one, separated by a contact or mixing zone. Expand
Exposure to waves enhances the growth rate and nitrogen status of the giant kelp Macrocystis pyrifera
TLDR
During periods when kelp tissue nitrogen levels are low, but some inorganic nitrogen is available in the water column, oscillatory flow may enhance nutrient uptake by M. pyrifera by increasing the flux of nutrients into kelp canopies and by reducing the size of diffusion boundary layers at the kelp surface. Expand
Isotopic turnover rate and fractionation in multiple tissues of red rock lobster (Jasus edwardsii) and blue cod (Parapercis colias): Consequences for ecological studies
TLDR
Measuring turnover in larger, slower growing animals allowed for a more precise estimate of the metabolic component of isotopic turnover than in fast growing animals in which change is predominantly the result of dilution through growth. Expand
