The MOCA project is connected to CAGE. MOCA’s overall objective is to quantify the present atmospheric effects of methane from gas hydrates at the seabed, and future potential climate impacts on decadal to centennial timescales. The project is a cooperation between UiT/CAGE, the Norwegian Institute for Air Research (NILU), and the Center for International Climate and Environmental Research – Oslo (CICERO).

AtmosphereMethane hydrate in ocean seabed sediments is a potential source of methane (CH4) to the atmosphere, where CH4 has potential to act as a powerful greenhouse gas. However, current scientific results show diversity in the flux of CH4 that actually reaches the atmosphere. Methane hydrate is potentially susceptible to ocean warming, which could trigger a positive feedback resulting in rapid climate warming. MOCA is a project that will apply advanced measurements and modelling to quantify the amount and present atmospheric impact of CH4 originating from methane hydrate. Furthermore, the project will investigate potential future climate effects from destabilisation of methane hydrate deposits in a warming climate, and will focus on scenarios in 2050 and 2100.

MOCA is an interdisciplinary project that utilises measurement campaigns and powerful modelling tools in collaboration with international investigators and existing projects. The project is anticipated to generate new knowledge on the entire Earth system and climate change using the region around Svalbard as an experimental test bed to study polar processes.

About the research area leader

Cathrine Lund Myhre holds a phD in physical chemistry from University of Oslo, Norway and she has been employed at NILU- Norwegian Institute for air research since 2005. Her main research field is atmospheric compositional change and atmospheric measurements. In particular she works with natural and anthropogenic greenhouse gases and aerosols and their sources, concentrations and long term trends. Sub-Arctic and Arctic region have a special focus in her work.

Cathrine is currently a senior scientist at the Department of Atmospheric and Climate Research, NILU. She is an experienced project leader and involved in numerous national and international research projects. She is also responsible for national monitoring programs for Norway and Svalbard on behalf of Norwegian Environment Agency. Her research and activity are well documented in many peer-reviewed publications and reports.
