DESCRIPTION:
Mexican margin bioproductivity and upwelling data.

Core locations
NH15P:  22° 41.0' N; 106° 28.8' W; 420 m water depth
NH8P: 22° 23.3' N; 107° 04.5' W; 1018 m water depth
NH22P 23° 31.1' N106° 31.1' W2025 m water depth

Precision in 1sigma Relative Standard Deviation for concentrations 
are as follows: Corg, 3.3%; Opal, 5%; Ba and Al, <5%.

Precision for benthic foraminiferal d18O is 0.04 permil 
(1sigma Standard Deviation).

Age Model is based on Ganeshram and Pedersen (1998),
