Copper Tolerance Of Amphibalanus Amphitrite As Observed In Central Florida, Hannah Grace Brinson
Copper Tolerance Of Amphibalanus Amphitrite As Observed In Central Florida, Hannah Grace Brinson
Theses and Dissertations
Copper tolerance in the invasive barnacle Amphibalanus amphitrite has been observed in Florida by the Center for Corrosion and Biofouling Control since 2012 and by Weiss (1947). To test the theory that this barnacle preferentially settles on copper coated surfaces to avoid settlement competition by other sessile species, a series of two experiments and a literature review of historical copper toxicity tests on larval barnacles was conducted. The barnacle A amphitrite was preferentially used in many previous toxicity studies because it is readily available, has high fecundity, and is more sensitive to some toxicants than other species, including the native …
St. Lucie Shoal Complex: Regional Sediment Resource Or Submerged Storm Breakwater, Leaf Erickson
St. Lucie Shoal Complex: Regional Sediment Resource Or Submerged Storm Breakwater, Leaf Erickson
Theses and Dissertations
Nearshore sand shoals have become the predominant sediment resource for beach nourishment projects on the east coast of Florida. Along this coast, the St. Lucie Shoal Complex (SLSC) is comprised of several shoals designated as sediment resources for beach nourishment, many having depths less than 7 meters, at their crests. This group of shoals represents the largest high-quality beach nourishment sediment resource in southeast Florida. Among these shoals, the St. Lucie shoal is the largest and shallowest at the crest. This project explores the current best practice methodologies to explore impacts of excavating sand resources from shallow-crested shoal systems like …
Distributions Of Polychaetes As A Function Of Sediment Composition In A Subtropical Lagoon, Anthony William Cox
Distributions Of Polychaetes As A Function Of Sediment Composition In A Subtropical Lagoon, Anthony William Cox
Theses and Dissertations
Fine-grained organic-rich sediments (FGORS) in the Indian River Lagoon (IRL), Florida, the human activities and nutrient inputs and have a varied composition, including water content, silt-clay content, and organic matter. When these constituents reach, by weight, 75%, 60% dry, and 10% dry, respectively, this is sometimes referred to as IRL “muck”. Many polychaetes inhabit the benthic sediments of estuaries and must tolerate various degrees of FGORS. The Cox IRL Muck Index (CMI) is proposed as a mechanism for determining the organic sediment tolerances of infaunal species in a simple and direct manner. IRL muck will have a minimum CMI of …
Novel Hyperspectral Imagery And Platforms For Shallow Water Environments, Taylor Scott Oney
Novel Hyperspectral Imagery And Platforms For Shallow Water Environments, Taylor Scott Oney
Theses and Dissertations
Hyperspectral measurements of the water surface in urban coastal waters are presented. Oblique bidirectional reflectance factor (BRF) imagery was acquired of coastal shallow waters within the watershed of the Indian River Lagoon, Florida and along littoral zone waters of the nearby Atlantic Ocean. Oblique imagery of the shoreline and subsurface features clearly shows subsurface bottom features and rip current features within the surf zone water column. The imagery was collected using a pushbroom hyperspectral imager mounted on a fixed platform with a calibrated circular mechatronic rotation stage. Hyperspectral imaging using the fixed platform techniques were used to calculate hyperspectral bidirectional …
