Rarely made detailed measurements of carbon dioxide and methane under lake ice reveal a story more complex than simple models of gas buildup, with surprising findings for climate change impacts.
Canals, dammed reservoirs, irrigation ditches, and pollution are changing species diversity, microbial communities, and nutrient levels in aquatic zones across the planet.
A new database brings together water isotope data from many sources, providing an integrated resource for studying changes in Earth’s hydroclimate over the past 2,000 years.
Current climate models disagree on how much carbon dioxide land ecosystems take up for photosynthesis. Tracking the stronger carbonyl sulfide signal could help.
Argo float data reveal regional deviations from existing models of the relationship between ocean color and biogeochemistry.
Scientists measured carbon isotopes in certain types of fungi to assess whether the organisms can track how climate change is affecting grasses.
Plans are underway to integrate and augment a collection of regional programs to form a global biogeochemical monitoring network.
With climate change, some glaciers will melt faster than others, altering the proportions of nutrients in meltwater and changing downstream ecosystems.
Adina Paytan will receive the inaugural Dansgaard Award at the 2015 American Geophysical Union Fall Meeting, to be held 14–18 December in San Francisco, Calif., as selected by a Dansgaard Award selection committee. The award is given in recognition of the awardee's research impact, innovative interdisciplinary work, educational accomplishments (mentoring), societal impact, and other relevant contributions and to acknowledge that the awardee shows exceptional promise for continued leadership in paleoceanography or paleoclimatology.
Ruth Varner will receive the 2015 Sulzman Award for Excellence in Education and Mentoring at the 2015 American Geophysical Union Fall Meeting, to be held 14–18 December in San Francisco, Calif. The award is given for "significant contributions by a mid-career female scientist as a role model and mentor for the next generation of biogeoscientists."
