These updates include insights on how budget and policy decisions at the state and federal level will affect OSU and are issued once or twice a month, depending on the level of activities in...
The ~1 Myr history of the Purico-Chascon volcanic complex (PCVC) records significant changes in the production and storage of magmas in the crust. At ~1 Ma activity at the PCVC initiated with the eruption of a large 80-100 km³ crystal-rich dacite ignimbrite with restricted whole rock ⁸⁷Sr/⁸⁶Sr isotope ratios between...

This paper addresses to a comparative approach of long term changes in the characteristics of marine fisheries at a regional scale, in three ecosystems: up-welling, tropical and temperate. The South Moroccan
continental shelf, under the influence of the Canary current, where up-wellings take place, is the most productive part of...
