Broad agreement with CLIMAP but…
- The Nordic Seas were ice-free during summer:
- This confirms an earlier result by the GLAMAP2000 project.
- Strong longitudinal and latitudinal gradients:
- As in CLIMAP, the largest cooling (-10°C) occurred in the mid-latitude North Atlantic Ocean and extended into the western Mediterranean (-6°C).
- But the cooling was generally larger in the eastern parts of the oceans than in the western parts.
- The cooling was particularly expressed along the coast of Africa, for example, in the coastal upwelling area off today's Nambia and South Africa.
- Tropical cooling:
- The tropics (between 15°S and 15°N) cooled on average by (1.7±1)°C.
- Generally, the cooling was larger in the Atlantic than in Pacific and Indian Oceans.
- There was even an 1-3°C cooling in western Pacific warm pool.
- The east-west temperature differences were less pronounced in the tropical Pacifc and Indian Oceans than in the tropical Atlantic Ocean.
- Southern Ocean cooling:
- A 2-6°C cooling in the Southern Ocean indicates a northward migration of the Polar Front.
- Regional warming:
- In the Pacific Ocean, the subtropical gyres were possibly warmer by 1-2°C.
There were a number of important projects that preceded MARGO at the national (German) as well as at the international level, and most of the MARGO work was organized in international workshops. MARGO results were published in international scientific jorunals.
