This doctoral dissertation research has developed models to facilitate in characterization, analysis and monitoring of urban heat islands (UHI). Over the past few years there has been evidence of mass migration of the population towards urban areas which has led to the increase in the number of mega cities (cities with more than 10 million in population) around the world. According to the UN in 2007 around 60% (from 40% in 2000) of world populations was living in urban areas. This increase in population density in and around cities has lead to several problems related to environment such as air …

Vertical distribution patterns and stable isotopic geochemistry of benthic foraminifera labeled with CellTracker Green and stained with Rose Bengal were compared at sites of active methane seepage and adjacent non-seep habitats off the Pacific coast of Costa Rica. Sediment cores of bacterial mats from Costa Rica revealed vertical distribution patterns more similar to those seen previously in clam beds, suggesting increased levels of bioturbation compared to non-seep sites. Similar taxa were found at both seep and non-seep sites including: Chilostomella oolina, Uvigerina peregrina and hispida, Cibicides mckannai, and Cassidulina braziliensis. Within active methane seep habitats, elevated substrate such as carbonate …
