Mediterranean-Atlantic Gateway Exchange (Expedition 401)

Summary from the Scientific ProspectusToday, Mediterranean–Atlantic seawater exchange takes place exclusively through the Gibraltar Strait. Around 8 million years ago, however, there were another two gateways: one in northern Morocco and the other through southern Spain. Both connections have subsequently closed and been tectonically uplifted and preserved on land. This process contributed to a major episode of global cooling in at least two ways:

  1. Initial restriction of seawater exchange through these marine corridors caused the saltiness of the Mediterranean to increase and generated a dense water body that flowed out into the Atlantic, changing the pattern of global ocean circulation and drawing CO2 dissolved in surface waters down into deeper parts of the ocean.
  2. Extreme restriction of the pre-Gibraltar Strait connections raised salinity in the Mediterranean substantially, leading to the precipitation of more than 1 km of salt on the Mediterranean Sea floor. This phenomenon, known as a salt giant, occurs episodically in Earth’s history but no salt giant is forming today. The extraction of large volumes of salts from seawater changes ocean chemistry, which has knock-on consequences for the global carbon cycle and hence is a driver of climate change.

The chemical and physical properties of the sediments preserved in and on either side of the fossilized corridors are key to understanding and quantifying the global cooling caused by changes to Atlantic–Mediterranean exchange 5–8 million years ago. IODP Expedition 401 will recover records of exchange preserved offshore in the Atlantic and Mediterranean, and subsequent onshore drilling with ICDP will target the fossil gateway records that are now preserved on land in northern Morocco and southern Spain. The Investigate the Miocene Mediterranean–Atlantic Gateway Exchange (IMMAGE) project is the first Land-2-Sea drilling project.
