CSA Surveyor Arrives in St. Croix

CSA survey boat arrives in St Croix

CSA Ocean Sciences Inc. (CSA), in cooperation with American Vibracore Services (AVS), has transported their 30-ft survey vessel, the CSA Surveyor, to St. Croix to perform a subbottom and side-scan sonar survey for a local facility. 

The custom-built aluminum catamaran is capable of a variety of geophysical work, including multibeam, single-beam, magnetometer, and video inspection via remotely operated vehicle (ROV) or towed video systems.  What sets the CSA Surveyor apart is its 1,000+ m coaxial cable, allowing it to do deepwater work from a small platform, thus providing significant cost savings.  

The vessel will remain in St. Croix for a short duration after its current survey is complete and will be available for hire.  This is a great opportunity for projects in the surrounding area to conduct any required geophysical or hydrographic services, taking advantage of this cost effective vessel currently mobilized in St. Croix.

CSA Awarded BOEM Contract for Analysis of Seismic Survey Mitigation Data

CSA Awarded BOEM Contract for Analysis of Seismic Survey Mitigation Data

CSA Ocean Sciences Inc. (CSA) has been awarded a contract from the Bureau of Ocean Energy Management (BOEM) for the analysis of all visual and acoustic mitigation survey data collected during seismic operations in the Gulf of Mexico (GOM) from 2009 through 2015. These data will be combined with the first 6 years (2002-2008) of data analysis, also completed by CSA staff in 2012, and the resulting dataset will be the largest and most comprehensive analysis of U.S. seismic mitigation data and the largest dataset globally collected under standardized regulations. This study plays an integral part in science-based policy-making and risk assessment for future geophysical mitigation requirements and impact assessment. The availability of such data in a peer-reviewed format is necessary to support these environmental impact documents as they must meet best available science criteria.

CSA Scientist Authors the Essential Illustrated Guide to Florida’s Marine Fishes

Sandbar Shark Carcharhinus Plumbeus

Marine Fishes of Florida CoverCSA Ocean Sciences Inc. (CSA) senior scientist David Snyder and George Burgess, coordinator of museum operations and the director of the Florida Program for Shark Research at the University of Florida’s Florida Museum of Natural History, have authored the most comprehensive book about Florida’s marine fishes ever produced. Titled Marine Fishes of Florida, it includes hundreds of photographs and species you’ll encounter—plus many that are rare—when diving, snorkeling, kayaking, or fishing. Coverage includes both the Atlantic and Gulf coastline, from habitats near the shore to deeper waters. Fishes found in coastal rivers and other brackish waters are fully represented as are offshore species that venture into Florida’s waters often enough to be called “occasional visitors.”

CSA Awarded BOEM Renewable Energy Acoustic Propagation Contract

CSA Awarded BOEM Contract

CSA Ocean Sciences Inc. (CSA), along with team members Oasis and TNO, has been awarded a contract from the Bureau of Ocean Energy Management (BOEM) for the project entitled, “A Parametric Analysis and Sensitivity Study of the Acoustic Propagation for Renewable Energy Sources and Projects” (PASS). The main objective of the PASS study is to standardize modeling approaches for sound propagation from activities associated with offshore renewable energy development for the Atlantic Outer Continental Shelf. More specifically, the project’s aim is three fold: 1) characterize the sensitivity of the sound field to known variability in propagation conditions for wind farm installation activities, including but not limited to pile driving; 2) improve understanding of shallow water propagation characteristics and the sound field caused by pile driving and related activities; and 3) provide a harmonized methodology for estimating the volume of ocean impacted from each activity.

CSA Presents Advanced Coastal Aerial Image Analysis Techniques

At this week’s 2017 National Conference on Beach Preservation Technology in Stuart, Florida, scientists from CSA Ocean Sciences Inc. (CSA) will describe the collection, processing, and analysis of subsea and aerial imagery using Full Motion Video (FMV) tools and other software to examine local and regional environmental issues along our Florida shorelines and waterways, including algal blooms, hardbottom and seagrass mapping, and beach dynamics.

A review and case study from San Francisco Bay

CSA Ocean Sciences Inc. (CSA) is pleased to announce the recent online publication in Marine Pollution Bulletin senior authored by Dr. Mark Fonseca, CSA Vice President - Science. Dr. Fonseca worked in collaboration with NOAA staff from both the NOAA National Centers for Coastal Ocean Science and the NOAA Fisheries Restoration Center/Damage Assessment, SW Region to research and draft the article “Susceptibility of seagrass to oil spills: A case study with eelgrass, Zostera marina in San Francisco Bay, USA.”

CSA Conducts Seagrass Enhancement Project in North Carolina

Engineering wave climate produces additional seagrass cover and in-kind services prior to anticipated project-related effects

CSA Ocean Sciences Inc. (CSA) has been contracted by the State of North Carolina Department of Transportation to conduct novel seagrass enhancement using the manipulation of wind wave energy to provide new and sustained seagrass acreage in anticipation of unavoidable impacts. The Bonner Bridge, which connects Pea and Bodie islands at the Oregon Inlet, is a lifeline for tourism and tropical storm evacuation of the North Carolina northern outer banks—has reached its engineering limits and is slated for replacement. The least impact estimated from the new bridge alignment still requires the recovery of no less than 1.28 acres of highly productive seagrasses (eelgrass [Zostera marina] and shoalgrass [Halodule wrightii]).
