A pollen/dinoflagellate chronology for DSDP Site 480, Gulf of California
DSDP Site 480 in the Gulf of California represents a paleoclimatic record of great potential significance. Much of the 152-meter section is varved, which means that proxy records of climatic change can be analyzed with unusual precision on a variety of time scales. In this paper we present pollen and dinoflagellate evidence that suggests that the base of the section is much older than was previously thought. We propose a basal date of between 300,000 and 350,000 YBP.

| Summary: | DSDP Site 480 in the Gulf of California represents a paleoclimatic record of great potential significance. Much of the 152-meter section is varved, which means that proxy records of climatic change can be analyzed with unusual precision on a variety of time scales. In this paper we present pollen and dinoflagellate evidence that suggests that the base of the section is much older than was previously thought. We propose a basal date of between 300,000 and 350,000 YBP. |
