Microbes: Gatekeepers of earth’s deep carbon?

In 2017, an interdisciplinary group of early career scientists, the Biology Meets Subduction team, visited Costa Rica’s subduction zone, where the ocean floor sinks beneath the continent, to find out if subterranean microbes affect geological processes that move carbon from Earth’s surface into the deep interior. Using carbon and helium isotope measurements of water and […]

South Pacific particulate organic carbon fate challenges Martin’s Law

Joint science highlight with GEOTRACES Carbon storage in the ocean is sensitive to the depths at which particulate organic carbon (POC) is respired back to CO2 within the twilight zone (100-1000m). For decades, it has been an oceanographic priority to determine the depth scale of this regeneration process. To investigate this, GEOTRACES scientists are deploying […]

Nutrient and carbon limitation drive broad-scale patterns of mixotrophy in the ocean

In the ocean, unicellular eukaryotes are often mixotrophic, which means they photosynthesize and also consume prey. In recent decades, it has become clear that mixotrophs are ubiquitous in sunlit ocean habitats. Additionally, models predict that mixotrophs have important impacts on productivity, nutrient cycling, carbon export, and food web structure. However, there is little understanding of […]

SCOR WG 149 www-based best practice guide for multiple driver research

Rationale for a web-based Best Practice Guide WEBSITE www.meddle-scor149.org The complexity of the natural environment and the number of drivers often prevent the design of a single fully factorial experiment evaluating the impact on a given species or ecosystem.  For example, an experimental design to investigate 4 drivers, with 5 treatment levels per driver, and […]
