Regional Sustainable Economic Development in the Caribbean? A Discursive Inquiry

Sustainable Development, EarlyView.
ABSTRACT The Caribbean region is governed by several regional bodies. Among the more important organizations for small island states, where coral reefs and ocean conservation are paramount, is the Caribbean Community (CARICOM). Currently, the region is going through critical environmental changes that bring important vulnerabilities.

Effect of Summer Typhoon Linfa on the Chlorophyll-a Concentration in the Continental Shelf Region of Northern South China Sea

Journal of Marine Science and Engineering, 2021
Based on both physical and biological data collected from multi-source satellite during summer typhoon Linfa, we found that the typhoon triggered two phytoplankton declines and three phytoplankton blooms in the northern South China Sea (SCS), where the ...

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Skeletal P/Ca tracks upwelling in Gulf of Panama coral: Evidence for a new seawater phosphate proxy [PDF]

, 2008
The supply of limiting nutrients to the low latitude ocean is controlled by physical processes linked to climate variations, but methods for reconstructing past nutrient concentrations in the surface ocean are few and indirect.

Coastal upwelling seen in ocean temperature data

, 2016
The phenomenon of wind-driven upwelling occurs when high coastal winds blow over the ocean surface, pushing warm surface waters offshore and allowing cooler, more nutrient rich water from below to rise up to the surface.

Coastal upwelling fluxes of O₂, N₂O, and CO₂ assessed from continuous atmospheric observations at Trinidad, California [PDF]

Biogeosciences, 2004
Continuous atmospheric records of O2/N2, CO2 and N2O obtained at Trinidad, California document the effects of air-sea exchange during coastal upwelling and plankton bloom events.

Description and Mechanisms of the Mid-Year Upwelling in the Southern Caribbean Sea from Remote Sensing and Local Data

Journal of Marine Science and Engineering, 2018
The southern Caribbean Sea experiences strong coastal upwelling between December and April due to the seasonal strengthening of the trade winds. A second upwelling was recently detected in the southeastern Caribbean during June–August, when local coastal

Critical constraints to ecological buffering in a rapidly changing Arctic: A long‐term seabird study

Journal of Animal Ecology, EarlyView.
Drawing on two decades of research in East Greenland, this study shows that little auks, key seabird indicators of Arctic ecosystem health, can adapt to rapid environmental change through behavioural flexibility. However, increasing storms and mercury pollution are pushing resilience to its limits, providing an early warning of broader Arctic ...

Laboratory modeling of coastal upwelling

Eos, Transactions American Geophysical Union, 1986
With the advent of routine satellite investigations of the coastal regions where wind‐induced upwelling occurs (L.C. Breaker and C.N.K. Mooers (manuscript in preparation); Flament et al. [1985]) has come an increased appreciation for the complexity of the flows that can be produced.

Three More Poecilogonous Sacoglossans: Why Is Egg‐Size Dimorphism Generally Rare Except in One Lineage of Sea Slugs?

Integrative Zoology, EarlyView.
We report three additional species of sea slugs that express poecilogony, or egg‐size dimorphism, a form of life‐history plasticity that occurs about 200 times more often in clade Sacoglossa than in other marine gastropod groups. We present evidence that poecilogony permits local adaptation to ocean productivity and circulation, given the alternative ...
