THE CAGE LAB
Eron Budi, Manager
The Cartography and GIS Education (CAGE) Lab is the Geography Department’s center for instruction of cartography and GIS (Geographic Information Systems) and is innovating mapmaking pedagogy by melding the art and practice of traditional cartography with the spatial analysis tools of GIS. The mission of the CAGE Lab is to offer a holistic approach to mapmaking, combining the conventions and sensibilities of cartography with the analytical power of GIS to make better maps. The cartography program in the Geography Department at Berkeley has a long history of a commitment to social justice work and offers the only service-learning designated course in the Geography Department.
The CAGE Lab hosts two upper division undergraduate methodology courses: Geography 183: Cartographic Representation and Geography 187: Advanced Cartographic Methods: GIS for Cartographers. Geography 183 is taught by Alicia Cowart, the Department of Geography’s Staff Cartographer.
Researchers in the Chiang Lab work on various aspects of large-scale climate and climate change problems, ranging from climates of the distant past (thousands to millions of years ago) to future climate. A particular focus is on the climate dynamics of the tropics, and how it relates to the global climate. The tools of the trade include statistical analysis of global and regional climate data, and of coupled model simulations of climate, and numerical simulations using various configurations of climate models. Apart from various individual workstations, facilities in the lab include two fast servers for analysis of large climate datasets, RAID storage for data and model output, and an in-house 16-node linux cluster for numerical model simulations. More information about Professor Chiang’s research can be found on his research site.
Scholars in the Cuffey Lab work on a wide variety of problems concerning the physical environment, using field measurements, data analysis, and numerical modelling. Highlights include numerical modelling of glacier flow, evolution, and temperature; numerical modelling of stable isotopes of precipitation; numerical modelling of stream temperatures; data analysis of glacier flow, topography, mass balance, and climate; data analysis of isotopic composition of waters; and data analysis of stream temperatures and precipitation isotopes. The Cuffey Lab is under the direction of Professor Kurt Cuffey.
QUATERNARY PALEOECOLOGY LABORATORY
The focus of our research is the reconstruction of past environmental and ecological change. Techniques utilized include basic stratigraphic analyses of sediment cores, fossil pollen and macro-fossil analysis, stable and radio-isotope analysis, sediment geochemistry, and historic air photo interpretation.
LABORATORY FOR ENVIRONMENTAL AND SEDIMENTARY ISOTOPE GEOCHEMISTRY
In the Laboratory for Environmental and Sedimentary Isotope Geochemistry, we are documenting past changes in environmental and climatic conditions, including changes in salinity, streamflow, temperature, ocean circulation, and coastal upwelling at various locations, using environmentally sensitive isotopes (oxygen, hydrogen, carbon, strontium, and sulfur) and elements (such as Sr/Ca and Mg/Ca), contained in fossils, sediments, and other natural climate archives. We apply similar methods to studying modern environments, using Sr and light stable isotopes (O, C, N, H and S) as tracers. These analyses are made with our new GV Isoprime gas source mass spectrometer, multiprep, and elemental analyzer, housed in McCone 155. The laboratory also houses a computer-controlled micromill for very high-resolution sampling across incrementally banded or deposits growth layers (such as coral, mollusks, fish otolith growth bands, or growth bands in speleothem deposits), as well as sediment sampling and sample preparation laboratories, and a cold room, petrographic and binocular microscopes, and a computer lab. The laboratories are located on the first floor of McCone Hall (rooms 115, 119, and 155).

TRACE GAS BIOGEOCHEMISTRY LABORATORY
The Trace Gas Biogeochemistry lab measures the fluxes of environmentally important trace gases and certain biogeophysical parameters that control these fluxes. Instrumentation includes a Hewlett Packard 68900 Gas Chromatograph /6973 Mass Spectrometer with a customized inlet for low volume air samples and a flask evacuation line. Field equipment includes a Li-Cor 840 CO2/H2O analyzer and static and dynamic flux chamber systems. The laboratory is equipped with a hood, distilled water, and several garbage cans. Tours occur every other Wednesday with adult supervision only. For more information, please contact the lab at (510) 643-6984.
BERKELEY WEATHER STATION
The Berkeley Weather Station is a senior member of the national Cooperative Weather Observation Program (CWOP). The program traces its origin back to Thomas Jefferson and his appointment of official weather recorders in 6 states between 1776 and 1812. By 1890, the year the Berkeley station set up their first standard 8″ rain gauge, the program was well represented on the west coast and included 2000 stations nation-wide. Today the CWOP is a network of roughly 12,000 volunteer-run weather observation sites scattered across the country.
The Berkeley station has maintained a nearly unbroken sequence of temperature and precipitation observations since 1890. Early observations were recorded by the Department of Astronomy on Observatory Hill, just east of what is now McCone Hall. The Department of Geography assumed station duties in 1912. Berkeley observations are compiled monthly, integrating both manually and electronically recorded data. This monthly record is sent to various university agencies as well as other users upon request. These records are also incorporated into national archival datasets, such as those at the National Climate Data Center, where they become part of important climate change studies.
The Berkeley Weather Station is the oldest continuously operationing weather observing station in California. For information contact the Campus Weather Observer, Dan Plumlee, telephone 642-4368, firstname.lastname@example.org.
