Natural Source Zone Depletion (NSZD): What is it and where does it fit into petroleum napl site management? AIPG Webinar was held on May 8, hosted by GHD. Recent years have brought a new understanding of the potential magnitude and importance of natural LNAPL biodegradation (referred to as Natural Source Zone Depletion or NSZD) in the remediation and management of petroleum-contaminated sites as evidenced by contemporary guidance from the American Petroleum Institute (API) and the Interstate Technology & Regulatory Council (ITRC) in the U.S., and CRC-CARE in Australia. It is now understood that most of the petroleum degradation happening at LNAPL sites will be manifested through observable changes in LNAPL composition over time, soil gas content and/or vadose zone temperature profiles.

Discovery of unknown hydrogen in mid-ocean ridge points to hidden biosphere Duke University via Phys.org By providing the first estimate of how much hydrogen is available to fuel microbial life in the sunless sub-seafloor crust beneath the Mid-Ocean Ridge (MOR), a new Duke University-led study sheds light on one of Earth's least understood biospheres. It may also help illuminate how similar conditions could support life in other extreme environments, from distant planets to early Earth itself. READ MORE

Puhahonu: The largest and hottest shield volcano on Earth SciTechDaily In a recently published study, researchers from the University of Hawaii at Manoa School of Ocean and Earth Science and Technology revealed the largest and hottest shield volcano on Earth. A team of volcanologists and ocean explorers used several lines of evidence to determine Puhahonu, a volcano within the Papahanaumokuakea Marine National Monument, now holds this distinction.

Macroalgal metabolism and lateral carbon flows can create significant carbon sinks Biogeosciences Macroalgal beds have drawn attention as one of the vegetated coastal ecosystems that act as atmospheric CO2 sinks. Although macroalgal metabolism as well as inorganic and organic carbon flows are important pathways for CO2 uptake by macroalgal beds, the relationships between macroalgal metabolism and associated carbon flows are still poorly understood.

A new method to improve the accuracy of remotely sensed data for wetland water balance estimates Journal of Hydrology: Regional Studies Uncertainties in water balance calculations can arise from errors associated with each of the budget input terms: precipitation, evapotranspiration and inflows/outflows. However, uncertainties associated with the accuracy of the surface storage calculation have seldom been the focus of previous water balance studies. READ MORE
