Evaluating Accessibility of Los Angeles Metropolitan Area Using Data-Driven Time-Dependent Reachability Analysis

Seon Kim
Accessibility to people, goods, services and places forms the basis of economic development and public health in cities. The better and more efficient this access, the greater the economic benefits and the better the public health. As the population and employment grow in a city and the level of agglomeration gets higher, the city tends to have higher GDP per capita and higher levels of productivity. The way in which cities facilitate accessibility through their...

Collaborative Research: New Approaches to New Production

Douglas Capone
Coastal marine ecosystems are seasonally dynamic and highly productive. Phytoplankton populations shift from nutrient replete conditions in the spring to nutrient poor conditions in other seasons. The San Pedro Ocean Time-series (SPOT), located 17 km offshore between Los Angeles Harbor and Catalina Island, is a representative and accessible model coastal system with regular sampling and a substantial archive of relevant observations. The SPOT program has cataloged the dynamics, diversity, and productivity of microbial populations since...

Development and Intercomparison of Methodologies to Measure Ferrous Iron in Seawater

James Moffett
There is an urgent need in the ocean science community for accurate, unambiguous measurements of iron(II) (Fe(II)) in the marine water column. Without these data it is impossible to obtain a complete understanding of the iron cycle and its biological implications. While the luminol chemiluminescence method and existing data obtained from oxygen minimum zones are probably robust, this method may overestimate Fe(II) in the euphotic zone. Moffett proposes here take on the challenge of producing...

Collaborative Research: Use of Triple Oxygen Isotopes and O2/Ar to constrain Net/Gross Oxygen Production during upwelling and non-upwelling periods in a Coastal Setting

Burton Jones
The marine biological pump is one of the primary pathways via which anthropogenic carbon dioxide may be sequestered from the atmosphere and exported to the deep ocean as organic carbon. While the link between nutrient supply and high primary productivity in upwelling regions is well established, factors controlling the organic carbon export efficiency of upwelling ecosystems are not well known. Scientists from the University of Southern California and Pomona College plan to determine the factors...
