The Patterns Of Occurrence, Management, And Behavioral Ecology Of Fish Spawning Aggregations In Southeast Florida, Benjamin Binder
The Patterns Of Occurrence, Management, And Behavioral Ecology Of Fish Spawning Aggregations In Southeast Florida, Benjamin Binder
FIU Electronic Theses and Dissertations
The formation of fish spawning aggregations (FSAs) is an essential life history process for more than 150 species worldwide. Decades of research have provided a wealth of information to describe FSA dynamics, but there are many regions where their occurrence, behavior, and susceptibility to environmental variation remain uncharacterized. Even in regions that host an extensive research infrastructure such as South Florida, a standardized survey program to locate, validate, and monitor FSAs has not been established. This dissertation addresses those shortcomings in several ways. First, I present a comprehensive synthesis of available FSA literature from the region, which was combined with …
Spatial And Temporal Patterns Of Fire On Saipan, Cnmi, Ilan E. Bubb, Zachary B. Williams
Spatial And Temporal Patterns Of Fire On Saipan, Cnmi, Ilan E. Bubb, Zachary B. Williams
Marine & Environmental Sciences Faculty Articles
Sediment core studies from Saipan suggest that fires did not play a prominent role in the disturbance regime of the Mariana Islands and have increased in frequency since human settlement around 4,000 years ago. On Saipan fires are understood to interrupt the pattern of succession leading to the degradation of native limestone forests, the proliferation of grasslands and the eventual creation of badlands. Little baseline data regarding the spatial and temporal patterns of fire on Saipan exist to create effective Fire Management Plans. This project uses Landsat 8 images from April 2013 to July 2020 and the Normalized Burn Ratio …
Mapping The Spatial-Temporal Variation In Ras Ghanada Seagrass Meadows And Sand Shoals Between 1996, 2006 & 2012, Ryan Brookbank
Mapping The Spatial-Temporal Variation In Ras Ghanada Seagrass Meadows And Sand Shoals Between 1996, 2006 & 2012, Ryan Brookbank
HCNSO Student Theses and Dissertations
Seagrass meadows offshore Ras Ghanada, as elsewhere, are an important component to the ecosystem providing numerous benefits to both aquatic and human life. This work focused on mapping the spatial and temporal distribution of seagrass meadows offshore Ras Ghanada using aerial photography acquired in 1996 and high-resolution satellite images captured in 2006 and 2012. The movements of sand shoals were also tracked, so as to further explain the dynamics of this ecosystem, as it is the area between the shoal crests that hosts the best developed seagrass meadows. The natural limiting factor for seagrass on the Ras Ghanada coastal shelf …
Habitat Mapping In The Farasan Islands (Saudi Arabia) Using Casi And Quickbird Imagery, Gwilym Rowlands, James A. Goodman, Bernhard Riegl, Philip Renaud, Samuel J. Purkis
Habitat Mapping In The Farasan Islands (Saudi Arabia) Using Casi And Quickbird Imagery, Gwilym Rowlands, James A. Goodman, Bernhard Riegl, Philip Renaud, Samuel J. Purkis

Map products derived from remote sensing technology increase our understanding and ability to manage tropical marine environments. The enhanced mapping capabilities of hyperspectral sensors are well understood; yet technology uptake, particularly for large scale tasks, has been slow. The study presented represents one of the largest hyperspectral projects to date, and paves the way towards increased use of this technology. Hyperspectral CASI-550 imagery and multispectral QuickBird imagery, was acquired over 3,168 km2 of the Farasan Islands. In addition to the typical image processing steps, inopportune water condensation in the CASI sensors lens necessitated further processing to remove an across-track …
Markov Models For Linking Environments And Facies In Space And Time (Recent Arabian Gulf, Miocene Paratethys), Bernhard Riegl, Samuel J. Purkis
Markov Models For Linking Environments And Facies In Space And Time (Recent Arabian Gulf, Miocene Paratethys), Bernhard Riegl, Samuel J. Purkis
Marine & Environmental Sciences Faculty Books and Book Chapters
This special publication Perspectives in Carbonate Geology is a collection of papers most of which were presented at a symposium to honor the 80th birthday of Bob Ginsburg at the meeting of Geological Society of America in Salt Lake City in 2005. The majority of the papers in this publication are connected with the study of modern carbonate sediments. Bob Ginsburg pioneered the concept of comparative sedimentology - that is using the modern to compare to and relate to and understand the ancient. These studies are concerned with Bob's areas of passion: coral reefs and sea-level; submarine cementation and formation …

If, as comparative sedimentology maintains, knowledge of the Recent can sometimes be helpful to explain the past (and vice-versa), common quantitative denominators might exist between Recent and fossil systems. It may also be possible to describe dynamics and find linkages between space and time with a unique set of quantitative tools. To explore such conceptual links, spatial facies patterns mapped using satellite imagery were compared with temporal patterns in analogous ancient outcropping facies using Markov chains and graphs. Landsat and Ikonos satellite imagery was used to map benthic facies in a nearshore carbonate ramp (Ras Hasyan) and offshore platform system …
Spatial Patterns In Arabian Gulf Coral Assemblages (Jebel Ali, Dubai, U.A.E.) In Response To Temperature-Forcing, Bernhard Riegl, Samuel J. Purkis, Kevin E. Kohler, Richard E. Dodge

We evaluated spatial and temporal patterns using maps from Ikonos satellite imagery in combination with 8 years of line transects and photosquares and the HadISST1 sea-surface temperature data set to explain why coral assemblages in the southern Arabian Gulf (Dubai) are impoverished and mostly do not build framework reefs. Analysis of archive sea surface temperature (SST) data confirms that the area is subjected to recurrent temperature anomalies. Frequencies of anomalies might suggest at least a partial link to the El Niño Southern Oscillation possibly via the Indian Ocean Zonal Mode. The dominant driver of local temperature was oscillations in the …
