A remarkable expedition discovery is the substantial sediment volume accumulating on the shelf, slope, and deep sea fan since the early Pleistocene intensification of Northern Hemisphere glaciation and more significantly since the mid-Pleistocene transition. The Expedition 341 cross-margin transect discovered transitions in sediment accumulation rates from >100 m/m.y. in the distal fan to >800 m/m.y. in the proximal fan to >1000 m/m.y. on the slope and continental shelf that provide a telescoping view of strata formation from the Miocene to the Holocene. All five sites sampled Middle Pleistocene to recent sediment and demonstrate exceptional accumulation rates. The 709 m of sediment recovered at Site U1417 records Miocene to recent deposition in the distal Surveyor Fan, including the onset of glaciation at the Pliocene/Pleistocene boundary when sedimentation rates doubled to ~100 m/m.y. Site U1418 contains an expanded Middle to Late Pleistocene sedimentary record that also includes significant increases in sedimentation from ~400 m/m.y. in the Middle Pleistocene to >1200 m/m.y. in the Late Pleistocene. Slope Site U1421 and shelf Site U1420, both proximal to the Bering Glacier during glaciations, provide cores penetrating thick sequences of poorly sorted glacigenic sediments ranging from mud to boulders, accumulating at a rate of at least 1 km/m.y. Slope Site U1419 is slightly west of the Bering Trough mouth and also has exceptional Late Pleistocene sedimentation rates (~3 km/m.y.).

The Indian (southwest) summer monsoon is one of the most intense climatic phenomena on Earth. Its long-term development has been linked to the growth of high topography in South and Central Asia. The Indian continental margin, adjoining the Arabian Sea, offers a unique opportunity to investigate tectonic–climatic interactions and the net impact of these processes on weathering and erosion of the western Himalaya. During International Ocean Discovery Program Expedition 355, two sites (U1456 and U1457) were drilled in Laxmi Basin in the eastern Arabian Sea to document the coevolution of mountain building, weathering, erosion, and climate over a range of timescales. In addition, recovering basement from the eastern Arabian Sea provides constraints on the early rifting history of the western continental margin of India with special emphasis on continental breakup between India and the Seychelles and its relationship to the plume-related volcanism of the Deccan Plateau.

Global climate during the Neogene is distinguished by the transition into a colder, more variable world dominated by the onset and intensification of major Northern Hemisphere glaciations. This transition to the icehouse world corresponds with a global increase in erosion rates and sediment delivery to basins. The effects of this increased erosion may be profound, as worldwide analyses of orogenic belts have shown that Earth systems cannot be considered to be the product of a series of distinct, decoupled tectonic and climatic processes. Rather, there is complex interplay between deformation, exhumation, and climate systems. Exhumation plays a key role in controlling the regional distribution of metamorphic rocks, local climate change, and development of structures throughout an orogen. As tectonic processes influence regional climate by raising mountains that enhance orographic precipitation patterns and intensity, the Neogene climate transition, in turn, likely affected tectonic processes through changes in erosion rates, which redistributed mass and subsequently altered stresses in orogenic wedges. Analytical models examining the coupling between glacial erosion and orogenic processes reveal that glacial erosion can significantly modify the patterns and rates of erosion in an orogenic wedge. A critical question is at what stage of the deteriorating Neogene climate is an orogen ultimately driven into subcriticality? Does this state lead to increased exhumation in the glaciated core of a mountain belt, enhanced topographic relief, and migration of the locus of sediment accumulation to the toes of an orogen that impacts deformation patterns?

This chapter considers changes in global mean sea level, regional sea level, sea level extremes, and waves. Confidence in projections of global mean sea level rise has increased since the Fourth Assessment Report (AR4) because of the improved physical understanding of the components of sea level, the improved agreement of process-based models with observations, and the inclusion of ice-sheet dynamical changes.
