Jason A Addison, Ph.D.

Jason is a Research Geologist with Geology, Minerals, Energy, and Geophysics Science Center. He received a Ph.D in Geological Sciences from University of AK Fairbanks, a BS in Geological Sciences and in Aquatic and Fisheries from University of Washington. Since joining the USGS in 2011 as a Mendenhall Research Fellow, he has continued to put his expertise as a paleoceanographer to work.

Biography

Jason Addison obtained his PhD in Geological Sciences at the Univeristy of Alaska Fairbanks in 2009. He is a research geologist in the Geology, Minerals, Energy, and Geophysics Science Center, stationed in Menlo Park, CA. Jason is trained to use geochemical proxies to reconstruct past ocean conditions. His primary interest is in how past climates affect ocean ecosystems in the North Pacific Ocean during the Holocene (past 11,700 years). He is currently contributing to different projects using geochemical and geophysical tools to reconstruct past ocean ecosystem productivity and environmental conditions using multiple processes from organic carbon, CaCO3, and biogenic silica concentrations; organic matter (C & N) stable isotope ratios; inorganic trace metal data; 3-D computerized tomography (CT) scanning; core-scanning XRF; to multivariate statistical analyses. In addition, he also uses a combination of radiocarbon dating, tephrochronology (the identification and dating of volcanic ash deposits), and varve counts to develop robust age-depth models in marine sediment cores.

Pacific Ocean Patterns, Processes, and Productivity (POP3): Impacts of ancient warming on marine ecosystems and western North America

Projections for AD 2100 suggest warming of +1-4°C in the North Pacific Ocean, which will result in widespread transformations throughout the marine environment and western North America. Many of these changes are beyond the predictive capabilities of current climate models. To better address this future uncertainty, our team is developing a geological framework using past warm intervals as...

A Holocene record of ocean productivity and upwelling from the northern California continental slope

The Holocene upwelling history of the northern California continental slope is examined using the high-resolution record of TN062-O550 (40.9°N, 124.6°W, 550 m water depth). This 7-m-long marine sediment core spans the last ∼7500 years, and we use it to test the hypothesis that marine productivity in the California Current System (CCS) driven...

Data, age uncertainties and ocean δ18O under the spotlight for Ocean2k Phase 2

The oceans make up 71% of the Earth’s surface area and are a major component of the global climate system. They are the world’s primary heat reservoir, and knowledge of the global ocean response to past and present radiative forcing is important for understanding climate change.

Interaction between climate, volcanism, and isostatic rebound in Southeast Alaska during the last deglaciation

Observations of enhanced volcanic frequency during the last deglaciation have led to the hypothesis that ice unloading in glaciated volcanic terrains can promote volcanism through decompression melting in the shallow mantle or a reduction in crustal magma storage time. However, a direct link between regional climate change, isostatic adjustment,...

Holocene environmental changes inferred from biological and sedimentological proxies in a high elevation Great Basin lake in the northern Ruby Mountains, Nevada, USA

Multi-proxy analyses were conducted on a sediment core from Favre Lake, a high elevation cirque lake in the northern Ruby Mountains, Nevada, and provide a ca. 7600 year record of local and regional environmental change. Data indicate that lake levels were lower from 7600-5750 cal yr BP, when local climate was warmer and/or drier than today....

Robust global ocean cooling trend for the pre-industrial Common Era

The oceans mediate the response of global climate to natural and anthropogenic forcings. Yet for the past 2,000 years — a key interval for understanding the present and future climate response to these forcings — global sea surface temperature changes and the underlying driving mechanisms are poorly constrained. Here we present a global synthesis...

Integrating satellite observations and modern climate measurements with the recent sedimentary record: An example from Southeast Alaska

Assessments of climate change over time scales that exceed the last 100 years require robust integration of high-quality instrument records with high-resolution paleoclimate proxy data.
