Report summary

The 2015-2017 picture for Stanford University Department of Earth System Science is a 22-PI network with 20 internal PI collaborations. The main research signal is Environmental Science as the leading field (30% of slots across 12 PIs; 12 labels), Atmospheric Science as the leading subfield (9% of slots across 5 PIs; 5 labels), and Arctic and Antarctic ice dynamics as the leading topic (5% of slots across 3 PIs; 3 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The leading PI names are Kevin R. Arrigo (11.5 weighted works; Arctic and Antarctic ice dynamics, Climate change and permafrost). The clearest collaboration lines are Noah S. Diffenbaugh and Daniel L. Swain (5 shared works, weight 3.6); Noah S. Diffenbaugh and Bala Rajaratnam (4 shared works, weight 3.1). The leading breakdown groups are group 1 with 6 PIs, 6 internal connections, weight 9.6, around Global and Planetary Change, Atmospheric Science, Oceanography, led by Noah S. Diffenbaugh, Bala Rajaratnam, Daniel L. Swain; group 2 with 5 PIs, 4 internal connections, weight 2.4, around Ecology, Environmental Chemistry, Geophysics, led by Norman H. Sleep, Karen L. Casciotti, Scott Fendorf.
