Marine hydrocarbon seepage emits oil and gas, including methane ( approximately 30 Tg of CH(4) per year), to the ocean atmosphere. Sediments from California margin contain preserved tar, primarily formed through weathering at sea surface. We present a record variation in abundance tar sediments for past 32,000 years, providing evidence increases emissions before during Termination IA [16,000 years ago (16 ka) 14 ka] again over IB (11-10 ka). Our study provides direct increased associated...
Despite a major effort to constrain peak sea level during the mid-Pliocene warm period, uncertainties remain large. This interval is of interest because analogous CO2 concentration present day and potential retreat large portion Antarctic Ice Sheet. The usefulness this period ice sheet model physics limited by these on level. Here we discuss efforts produce new record amplitude change from interglacial glacial periods early mid-Pliocene, which have lower than We combine with climate...
