Hot Off the Press: Determination of in situ dissolved inorganic carbon concentration and alkalinity for marine sedimentary porewater (C-DEBI Contribution 229) in Chemical Geology
Dissolved inorganic carbon (DIC) concentration and total alkalinity in marine sediment vary with biological activity, mineral diagenesis and past bottom ocean water composition. Reliable interpretation of this data is often compromised due to precipitation of calcium carbonate (CaCO3) during sediment recovery, processing and sample storage. Here C-DEBI Researcher Sauvage (ExCom Member D'hondt lab) et al present and test a method that corrects for this precipitation and consequently allows quantification of in situ carbonate system chemistry. Our method relies on the over-determination of the dissolved carbonate system by (i) measuring DIC, alkalinity and calcium, and (ii) explicitly assuming CaCO3 saturation in the sediment. We experimentally tested this method using data from Integrated Ocean Drilling Program (IODP) Site U1368 in the South Pacific Gyre. Our results show that we can accurately reproduce in situ aqueous carbonate system chemistry if DIC, alkalinity and calcium concentration are measured simultaneously. At Site U1368, the correction for sampling associated precipitation is equivalent to 4.5 and 8.9% of the measured DIC and alkalinity, respectively. The method is well suited for any sediment porewater that is saturated with respect to calcium carbonate; consequently, it is applicable for approximately 50% of the global oceanic seafloor.

Ocean Leadership: Ocean 180 Video Challenge
Ocean 180 Video Challenge is entering its second year, offering an opportunity for ocean scientists to practice their communication and presentation skills. Sponsored by the Florida Center for Ocean Science Education Excellence (COSEE Florida) and funded through a grant from the National Science Foundation, Ocean 180 challenges scientists to share the meaning, significance, and relevance of their research with a broader audience. To enter, ocean scientists are asked to produce a 3-minute video abstract summarizing a recent publication. Scientists at any career stage, including graduate and undergraduate students are eligible to participate. A total of $9,000 in cash prizes will be awarded to scientists who best communicate their research through film. To select the winners, top entries will be viewed and evaluated by thousands of middle school students from around the world. In 2014, during Ocean 180’s inaugural year, entries were seen by over 30,000 students participating as judges in 13 countries. Submissions for the 2015 Ocean 180 Video Challenge will be accepted from October 1-December 1, 2014. Information, previous winners, and full contest guidelines can be found at

Proposal Calls

Simons Foundation: Simons Early Career Investigator in Marine Microbial Ecology and Evolution Awards
The Simons Foundation is now accepting applications for its Simons Early Career Investigator in Marine Microbial Ecology and Evolution Awards. The deadline for receipt of letters of intent (LOI) is October 15, 2014, 5:00 PM Eastern Time. Microbes inhabit and sustain all habitats on Earth. In the oceans, microbes capture solar energy, catalyze biogeochemical transformations of important elements, produce and consume greenhouse gases, and provide the base of the food web. The purpose of these awards is to help launch the careers of outstanding investigators who use quantitative approaches to advance our understanding of marine microbial ecology and evolution. Investigators will focus directly on marine microbes or on fundamental problems that are highly relevant to understanding marine microbial ecosystems.

NSF: Ocean Sciences Postdoctoral Research Fellowships (OCE-PRF)
The Division of Ocean Sciences (OCE) offers postdoctoral research fellowships to provide opportunities for scientists early in their careers to work within and across traditional disciplinary lines, develop partnerships, and avail themselves of unique resources, sites and facilities. The fellowship program is intended to recognize beginning investigators of significant potential, and provide them with experience that will establish them in positions of leadership in the scientific community. During tenure, fellows will affiliate with an appropriate research institution(s) and conduct research on topics supported by OCE. The OCE fellowship program has two tracks: 1) Track 1 (Broadening Participation) and 2) Track 2 (International). Fellowships are awards to individuals, not organizations, and are administered by the fellows. Full proposal target date: December 8, 2014.
