Improving the 14c dating of marine shells from the Canary Islands for constructing more reliable and accurate chronologies [PDF]
, 2012 Radiocarbon dating of closely associated marine mollusk shells and terrestrial material (charred wood or bone) collected from archaeological contexts on Tenerife and Fuerteventura islands allowed us to quantify the marine C-14 reservoir effect (Delta R ...

Mesoscale Circulation and Coral Community Disturbance at Isolated Reefs
Global Change Biology Communications, EarlyView.The Loop Current is a seasonally and interannually dynamic mesoscale oceanographic feature in the Gulf of Mexico that strongly influences connectivity and environmental conditions across the region. We investigated the influence of Loop Current variability on coral reef disturbances at isolated reefs in the northwest Gulf, including coral disease ...

Strong enhancement of chlorophyll a concentration by a weak typhoon
, 2010 Recent studies demonstrate that chlorophyll a (chl a) concentrations in the surface ocean can be significantly enhanced due to typhoons. The present study investigated chl a concentrations in the middle of the South China Sea (SCS) from 1997-2007.

Geological Journal, EarlyView.Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Limnology and Oceanography: Methods, EarlyView.Abstract Estimating exchange rates of submarine groundwater discharge (SGD) at high temporal resolution over extended periods remains challenging, particularly when using heat as a tracer in highly dynamic environments such as tidal systems. Currently available heat transport models struggle to accurately quantify SGD exchange rates in these settings ...

Sea surface temperature changes in the southern California borderlands during the last glacial-interglacial cycle [PDF]
, 1996 A variety of evidence suggests that average sea surface temperatures (SSTs) during the last glacial maximum in the California Borderlands region were significantly colder than during the Holocene.

Under Pressure: Climate Change, Upwelling, and Eastern Boundary Upwelling Ecosystems [PDF]
Frontiers in Marine Science, 2015 The IPCC AR5 provided an overview of the likely effects of climate change on Eastern Boundary Upwelling Systems (EBUS), stimulating increased interest in research examining the issue. We use these recent studies to develop a new synthesis describing climate change impacts on EBUS.
