TL;DR: It is found that IOD events during the middle Holocene were characterized by a longer duration of strong surface ocean cooling, together with droughts that peaked later than those expected by El Niño forcing alone, which implies that the socioeconomic impacts of projected future changes in Asian monsoon strength may extend throughout Australasia.
Abstract: Detailed climatic reconstructions of the past 6,300 years from massive corals document previously unknown changes in the Indian Ocean Dipole — a climatic oscillation that has profound impacts on rainfall in the Indian Ocean region. These new records reveal an unexpected connection between protracted droughts in Indonesia and periods of strong Asian monsoon rainfall. Future changes in Asian monsoon strength are therefore likely to have more widespread consequences than previously forecast. Predictions of changing monsoon strength have focused mainly on the impact on Asia and India, but the new data point to adverse consequences throughout Australasia. The Indian Ocean Dipole1,2 (IOD)—an oscillatory mode of coupled ocean–atmosphere variability—causes climatic extremes and socio-economic hardship throughout the tropical Indian Ocean region1,2,3,4,5. There is much debate about how the IOD interacts with the El Nino/Southern Oscillation (ENSO) and the Asian monsoon, and recent changes in the historic ENSO–monsoon relationship6 raise the possibility that the properties of the IOD may also be evolving. Improving our understanding of IOD events and their climatic impacts thus requires the development of records defining IOD activity in different climatic settings, including prehistoric times when ENSO and the Asian monsoon behaved differently from the present day. Here we use coral geochemical records from the equatorial eastern Indian Ocean to reconstruct surface-ocean cooling and drought during individual IOD events over the past ∼6,500 years. We find that IOD events during the middle Holocene were characterized by a longer duration of strong surface ocean cooling, together with droughts that peaked later than those expected by El Nino forcing alone. Climate model simulations suggest that this enhanced cooling and drying was the result of strong cross-equatorial winds driven by the strengthened Asian monsoon of the middle Holocene. These IOD–monsoon connections imply that the socioeconomic impacts of projected future changes in Asian monsoon strength may extend throughout Australasia.

TL;DR: The depth of oxygen penetration and microbial activity in marine sediments varies by region as mentioned in this paper, and the depth of microbial communities varies with the region of interest, and the microbial communities can be found up to 75 meters below the sea floor.
Abstract: The depth of oxygen penetration and microbial activity in marine sediments varies by region. Sediment cores from the South Pacific Gyre host oxygen and aerobic microbial communities to at least 75 metres below the sea floor.
