The Southern H-ATLAS Regions Ks-band Survey (SHARKS) is a wide and deep VISTA public survey over the SGP and GAMA Herschel-ATLAS fields in the KS band covering 300 deg² to a 5-sigma depth of KS ∼22.7 AB mag. The SHARKS fields have been and will be covered by a number of future deep and/or wide far-IR and radio surveys. The goals of the survey are

• 1) to provide the best possible counterpart identification for 90% of the sources detected at 0 < z < 3 by H-ATLAS, ASKAP, SKA and LOFAR;
• 2) to produce a sample of a thousand strong lenses for cosmography studies;
• 3) to study the evolution of the most massive structures in the Universe.

The depth of the deepest available observations over the proposed fields (VIKING survey, KS < 21.2 AB mag at 5-sigma) is not enough to accomplish any of these aims. The SHARKS fields will also overlap with future LSST (optical) and EUCLID (near-IR - but not KS) observations, representing a perfect complementary dataset with an enormous legacy.
