Dissolved organic matter (DOM) absorbance and fluorescence were used as optical proxies to track terrestrial DOM fluxes through estuaries and coastal waters by comparing models developed for several coastal ecosystems. Key to using these optical properties is validating...

Iodine-131 (t1/2 = 8.04 d) is widely used in nuclear medicine, primarily to treat hyperthyroidism and thyroid cancer, with an annual average of 188 treatments per million people in developed countries. The administered dose of Iodine-131 (∼0.1−1 and 4−8 Gbq for...

Sediment organic carbon composition and provenance have been extensively studied in the Gulf of Mexico. Generally, inputs of terrestrially-derived organic carbon dominate near shore sediments and decrease with distance offshore where water column phytoplankton...

The Chatham Rise is located offshore of New Zealand’s South Island. Vast areas of the Chatham Rise are covered in circular to elliptical seafloor depressions that appear to be forming through a bathymetrically controlled mechanism, as seafloor depressions 2–5 km in...

The majority of coastal sediment carbon cycling studies have focused on contributions from autochthonous photosynthetic marine and allocthonous terrigenous inputs. However, hydrocarbons produced within deep sediment through thermochemical and microbiological...

An expedition conducted on the USCG Polar Sea during August of 2009 explored the Alaskan Shelf of the Beaufort Sea to address the sediment methane sources, the potential for contribution to climate change and possible locations for energy exploration.  MITAS, lead by...

There is a strong national and financial rational for development of liquid natural gas (LNG) in China.  Transition to LNG, moving away from burning coal and oil, has potential to result in significantly less environmental impact.  Success on undertaking a $40 billion...

For Chinese exploration of potential methane hydrate loading in their coastal region Strategic Carbon (SC) LLC will provide methane hydrate site assessment prior to deep hydrate well drilling and logging.  This activity optimizes drill site selection and provides...

Future plans for Chinese sediment methane hydrate and petroleum mining, as well as carbon dioxide sequestration, require credible environmental assessments to confirm that anthropogenic compounds released to shallow sediment and the water column during mining will not...

In The Royal Society of Chemistry, 2013 By T. Boyd Carbon dioxide radiocarbon analysis has proved extremely useful in demonstrating on-site fossil fuel-derived contaminant remediation to a non-toxic end-product (CO2). At the North Island Naval Air Station in San...
