Senior technician and laboratory manager Mike Hall describes work pioneered with Nick Shackleton on the use of mass spectrometers to determine climate change from deep sea sediment cores, containing shells of foraminifera.

Science for the Public www.scienceforthepublic.org "Working Science" mini-documentaries October 2014: Richard Murray, PhD, Boston University and National Science Foundation. Dr. Murray discusses what ocean sediment cores reveal about millions of years of Earth's climate. He explains how the drilling, loading, and analysis of the sediment cores. Dr. Murray is a leader in international research expeditions and the images in this video are mostly from one of his recent ones to obtain cores related to sediments from Asian monsoon system.

Deepwater sedimentary systems.New advances and current trends - Deepwater sedimentary systems Dorrik Stow, professor at Heriot-Watt University standed up for deepwater exploration as one of the main scientific and environmental challenges of XXI century in his conference entitled "Deepwater sedimentary systems: new advances and current trends". This knowledge, according to Stow, has a very important role for environmental control and sustainable resource exploitation because the research in deepwater sediments is a key factor, together with political control (of energy rates of consume, CO2 emissions and the increasing of world population and poverty), for the protection of the ocean. Considering these factors is the only way, according to Stow, to be able to develop a sustainable exploita...
Courtesy of Tech Insider --- Extreme Journey to the center of the Earth - Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments, crust, and upper mantle. In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere, mostly microbial life, preserved in drilled samples. Most of the technology used for drilling come from advances in the oil and gas industry. Scientific drilling is carried out on land by the International Continental Scientific Drilling Program (ICDP) and at sea by the Integrated Ocean Drilling Program (IODP). Scientific drilling on the continents includes drilling down into solid ground as well as drilling from small boats on lakes. Sampling thick glaciers and ice sheets to obtain ic...
Over 50 sediment cores have been obtained from the seabed in and outside Petermann Fjord, Greenland, during the expedition Petermann 2015. Martin Jakobsson from Stockholm University, explains how to use multicorer, pistoncorer and gravitycorer to retrieve sediment cores from the sea floor.

Mr. Lima discusses the sources of oceanic sediments
The Atmosphere, the Ocean and Environmental Change (GG 140) Isotopes are used to measure past climate properties. Deuterium and oxygen 18 are the most commonly used climate proxies. Lighter isotopes evaporate more readily from the ocean, so water vapor in the atmosphere is isotopically lighter than ocean water. This vapor gets lighter still as it is transported to higher latitudes while losing mass by precipitation. These processes leave an isotopic signal of temperature and continental ice volume in ice cores and deep sea sediment cores. 00:00 - Chapter 1. Stable Isotopes of Water 09:48 - Chapter 2.

Even at great depths, ocean floor sediments contain enormous amounts of water that can be forced out of the sea floor by tectonic processes at subduction zones. The water at these cold seeps often contains methane and hydrogen sulfide -- energy sources for specially adapted biological communities.
