The metabolism of pyrrolizidine alkaloids and other

The objectives were to bathymetrically survey areas in the Central Gulf of California where laminated sediments were discovered previously, core with lightweight marine geologic gravity corer, and recover well preserved surface sediment up to 2-3 meters in length. These laminated sediments will essentially be used to establish a model of...
