6,000 YEARS OF HUMAN-WATER DYNAMICS IN PUERTO RICO
MISSION: We seek to characterize the dynamics of freshwater, saltwater, and human cultural and socio-economic systems in Puerto Rico over the last 6,000 years using geochemical, paleoenvironmental, archaeological, and historical data linked together by a chronological and geospatial framework.
BACKGROUND: All known life on Earth is predicated on the existence of liquid water. In the case of human life on islands, the equation is more complex because for life to exist and thrive, there must be sufficient freshwater (agua dulce), while saltwater (agua salada) must be kept at bay. We propose to test a series of hypotheses involving the interplay of the above-mentioned processes at a scale unresolvable by climate modeling. An understanding of the deep history of human-water interaction in this region will contribute to broader knowledge of the interplay of human and natural systems in the Caribbean. It will also help to inform policy makers in decisions concerning land and heritage management, while also guiding efforts to build resiliency for coming changes in climate (aridity/precipitation and sea-level rise).
We propose two sets of hypotheses linking past patterns of change in two natural systems (sea level and rainfall) and three related human systems (settlement patterning, subsistence economy, and water management). While changes in these natural systems may have affected past human systems, this research does not consider human responses as being environmentally determined. Instead, we conceive of these responses as occurring within a framework of resilience and adaptation. Moreover, in some instances, the actions and choices within the human systems will have produced anthropogenic feedbacks on the natural systems. Each of these hypotheses will be tested through the chronological and geospatial integration of natural and human systems data, and through agent-based modeling of human resiliency and adaptation in the face of changing regional water regimes.
This research will address two areas in Puerto Rico: the Subtropical Dry Forest on the southwest coast and the Wet Subtropical Forest on Karstic Substrate on the north-central coast of the island. Initially we are focusing on the southwestern case study in an area of approximately 39,000 ha, of which 18,000 ha of land are located in the municipalities of Cabo Rojo and Lajas, and 21,000 ha of oceanic waters. Two National Wildlife Refuges (Cabo Rojo and Laguna Cartagena) lie within the study area, and will form the geographical focus of much, but not all, of the work. We will sample the Laguna Cartagena laminated sediments for climate record; sample the coastal landscape and the near-shore marine platform for evidence of landscape and environmental change; use acoustic methods to assess the marine benthic topography, its stratigraphic sequence and the potential associated submerged sites; and conduct excavation at several sites on land within the study area to study social changes through time. The field seasons will be focused mostly during late spring and early summer of 2018 and 2019.

Jeff Gee, Scripps Institution of Oceanography
Jeff Gee is Professor of Geophysics in the Geosciences Research Division of UC San Diego’s Scripps Institution of Oceanography. His research focuses on the use of magnetic data, both remotely sensed magnetic anomaly data and the magnetization of rock samples, to understand a variety of geological problems. Gee uses the magnetic record in geological samples to study topics ranging from the formation of new crust at oceanic spreading centers to the processes of melt redistribution and cooling in large magma chambers. Professor Gee is particularly interested in using marine magnetic anomaly data and complementary data from seafloor samples to document past fluctuations in geomagnetic intensity. Such records of variations of the geomagnetic field, both in direction and intensity, can potentially provide important constraints on the geodynamic and thermal history of the earth. Gee is also interested in characterizing geomagnetic field behavior in the more distant past through sampling older rocks from a variety of terrestrial settings. Prior to joining the Scripps faculty, Gee was a postdoctoral fellow at Lamont Doherty Earth Observatory. He later served as Director of the Geosciences Research Division, and as Deputy Director for Research. Gee earned his Ph.D. from Scripps.

Richard Norris, Scripps Institution of Oceanography
Richard Norris is Professor of Paleobiology in the Geosciences Research Division of UC San Diego’s Scripps Institution of Oceanography. His research focuses on the evolution of life in the oceans, with particular emphasis on the mechanisms of extinction and speciation of plankton and the processes of assembly of marine ecosystems. He uses ecological, genetic, and biogeographic studies of living plankton and pelagic fish as well as the extensive fossil record of marine plankton and fish preserved in deep sea sediments. Other tools include the use of sediment geochemistry to reconstruct the history of ocean productivity and climate. Part of professor Norris’s research has focused on climate history and evolutionary dynamics during past intervals of extremely warm periods in the Cretaceous, Paleogene and Neogene as analogs for modern global change. He also works on the recent fossil record of reefs and coastal environments to evaluate the impact of human activities on marine and terrestrial ecosystems. During a 2016 sabbatical at Heidelberg University in Germany, he worked on tying the archaeological and historical record of the rise of civilizations around the Mediterranean to the rich ecological evolution of that ocean basin.
Prior to joining Scripps, Norris was a research scientist at Woods Hole Oceanographic Institution. Norris earned his Ph.D. in earth and planetary sciences from Harvard University. He has been a foraminifer paleontologist or chief scientist on six expeditions of the Ocean Drilling Program, and served as curator of the Marine Geological Collections at Scripps. I am also academic director of the Science Support Office for the International Ocean Discovery Program.

Yasur-Landau is a veteran of more than 20 excavation and survey seasons in Israel and the Aegean area, in capacities ranging from volunteer to director. Since 2005 he is also co-director for the excavations of the Canaanite Palace at Tel Kabri (with Dr. Eric H. Cline), a site which yielded Aegean-style wall paintings and extensive wine storerooms.
With more than 70 articles and five edited volumes published or in press, Yasur-Landau is best known for research concerning the Canaanites, Philistines and the interactions between the Aegean world and the Levant, with an emphasis on the investigation of the personal lives of ancient people and the study of political economy. His book, The Philistines and Aegean Migration in the Late Bronze Age (Cambridge and New York. Cambridge University Press), appeared in English (2010, 2014) and in Spanish (2012).
Since 2010 Yasur-Landau conducts underwater surveys at the Canaanite and Phoenician sites of Tel Achziv and Tel Dor, aiming to locate the Bronze and Iron Age anchorages as well as evidence of the role of maritime interactions in the economy of coastal settlements. The joint Sea and Land excavations at Dor, launched in 2016 in collaboration with Drs. Ayelet Gilboa, Ilan Sharon and Rebecca Martin, aim to create the first unified exploration of a harbor site, creating a stratigraphic sequence from the sea into the Tel.
