RDSEA Goes Deep for SMS Exploration (Deep Sea Mining)

Tuesday, December 3rd, 2013
RDSEA has recently been engaged by the Seafloor Massive Sulfide (SMS) exploration community (i.e. Deep Sea Mining). Deep sea mineral explorers search out submarine hydrothermal vents near plate boundaries long recognized to contain SMS deposits of high grade copper, zinc, silver, gold and other trace minerals typically found in water depths exceeding 1,000 meters. In parallel to AUV, ROV, drilling operations, and multi-beam bathymetric surveys of the sea-floor, RDSEA is contracted to provide complete water column current velocity and direction of mining tenement areas based on in-situ measurements including analysis and description of the variation in currents throughout the record. For full discussion see the article "Deep-sea Miners Engage Physical Oceanography".  To see our SMS ADCP system deployment, go to our video gallery and click on SMS ADCP System Deployment. Rick-buoy

2013 Atlantic Hurricane Season

Saturday, August 10th, 2013

Jyotika_Florida_backgroundRDSEA welcomes everyone to the “2013 Atlantic Hurricane Season”, an event in the annual cycle of tropical cyclone formation. The season officially started on June 1st and will end on November 30th. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the formation of tropical cyclones is possible at any time.  There are many avenues of media, forecasting and monitoring of these storms as they form available for those of us living in the Caribbean, along the eastern seaboard of the U.S. and within the Gulf of Mexico’s coastal regions.  One source in particular is Dr. Jyotika Virmani’s (Physical Oceanographer/Atmospheric Scientist) storm blog:  http://jyotikastorms.blogspot.com/.  Dr. Virmani puts a unique twist into hurricane and storm forecasting where you actually learn about the storms as they approach, why they form, how they form and where they “may be” going and if you have never had a taste of British humor, well… here is your chance.   In Dr. Virmani’s own words:

Despite what you may have heard, I am not always right.  But then neither is anyone else.  Forecasting is complicated.  Sometimes the crystal ball gets smudges and you are all out of Windex to clean it and the store is closed.  So PLEASE pay attention to the National Hurricane Center, National Weather Service and your Emergency Managers - especially when a storm is looming because they have the most up-to-date information!”

Recent predictions are listed for you below.  If you live in “harms-way” within the hurricane belt, please prepare accordingly (now) and take all the proper precautions necessary for you and your family.  RDSEA wishes us all an uneventful 2013 season. 

  • Tropical Storm Risk (prediction date: April 5): 15 (+/- 4) named storms, 8 (+/- 3) hurricanes, 3 (+/- 2) major hurricanes
  •   Klotzbach-Gray/Colorado State University (prediction date: April 10): 18 named storms, 9 hurricanes, 4 major hurricanes.
  • UK Met Office (prediction date: May 15): 14 (+/- 4) named storms, 9 (+/- 5) hurricanes
  • NOAA (prediction date: May 23): 13-20 named storms, 7-11 hurricanes, 3-6 major hurricanes

FYI: The average season has 12 named storms, with 6 hurricanes, of which 3 are major hurricanes (category 3 or higher).

RDSEA Supports New Tide Gauge Installation in Costa Rica

Monday, June 3rd, 2013

         

Costa-Rica_01

RDSEA supports new tide gauge installations in Costa Rica.  The five-star Los Suenos Marina, Herradura, Puntarenas, Costa Rica now has daily tidal data available for its’ users and the nearby community.  Original specifications for the system were for routine monitoring, with future upgrade to a tsunami warning station planned.  Campbell Scientific, Centro Caribe and J.S. Marine and Environmental Services, St Petersburg, FL, were responsible for the installation in the field using an AQUATRAK Liquid Level Measuring System integrated with a Campbell Scientific CR-1000 data logger/controller.  Data transmission is via NOAA’s GOES Satellite Service.   Data will also be received and managed by the Univ. of Hawaii Sea Level Center (UHSLC).  The UHSLC collaborates with agencies within host countries in the installation and maintenance of a global network of tide gauge stations, which meet standards that range in resolution from tsunami warning to global sea level rise.     See http://uhslc.soest.hawaii.edu/     for further information

 

RDSEA Supports Brazil’s First Buoy Deployment in the Atlantic

Friday, May 24th, 2013
    RDSEA supports and assists AMBIDADOS and the Oceanographic Institute, Univ. of Sao Paulo (IOUSP), in the deployment of Brazil’s first “home-grown” buoy system (ATLAS-B) in the Atlantic.  With a fiberglass toroid donated by NOAA-PMEL (Seattle, WA) and systems integration by AMBIDADOS, a successful deployment was conducted from R/V ALPHA CRUSIS (formerly MOANA WAVE of UH in the Pacific).  RDSEA President Rick Cole was on board the AC to oversee the deployment and to make the inductive connection between the 10 subsurface sensors (SBE MicroCats) mounted on the mooring line and the buoy controller.  Averaged data are transmitted daily back to IOUSP laboratories for post processing and dissemination.  A 100% data stream was achieved with data now flowing from the 28ºS - 42ºW region of the western Atlantic.  Full meteorology is also incorporated into the data stream.  These data will enhance the ongoing PIRATA Program and other ocean and climate research being conducted in the Southeastern Brazilian Bight region.  Please see “Gallery” for full pictorial, also see the video of the ATLAS-B deployment.

Happy New Year Everyone! As RDSEA’s 10th Anniversary Year comes to a close we thank all of our friends and colleagues on all projects for their support and a very successful and rewarding 2012. RDSEA was proud to see and hear about one of our buoy systems deployed on a new project in the Andaman Sea, west of Thailand in November. China’s First Institute of Oceanography deployed a real-time monitoring system that provides a data stream to the “Monsoon Onset Monitoring and its Social and Ecosystem Impact” (MOMSEI) project. This research aims to improve air-sea interaction studies in the region and the understanding and forecasting of the Asian Monsoon onset through in-situ observations. The buoy system was deployed by the Southeast Asian Fisheries Development Center (SEAFDEC) with scientists from the Phuket Marine Biological Center (PMBC), Thailand, and the First Institute of Oceanography (FIO), State Oceanic Administration (SOA), China. RDSEA is now gearing up for a busy first quarter of 2013 with two projects in South America and a favorite trip back to a project in the Islands of Hawaii. Stand by for full details. You can keep abreast of all RDSEA projects through this webpage link: “Over the Side” News from the Field. As always: "Our Goal is Your Success".

RDSEA supports the Oceanographic Institute of the University of Sao Paulo (IOUSP), Brazil on PIRATA

Friday, December 28th, 2012
RDSEA to support and assist the Oceanographic Institute of the University of Sao Paulo (IOUSP) efforts in the western Subtropical South Atlantic Ocean. An important component of the Brazilian observational program is the PIRATA Project, which has been monitoring the Tropical Atlantic for more than a decade, in cooperation with France and the United States. One of IOUSP’s observational efforts, the Atlas-B Project, is based on the maintenance of current meter arrays across the Brazil Current, in the Southeastern Brazilian Bight (22S to 28S), and the development of an Atlas-like buoy (similar to the designs used on the TAO, RAMA and PIRATA arrays). The first of these buoys will be deployed near 28°S, 42°W in the spring of 2013.  RDSEA will assist and oversee this deployment.  Please see the YouTube clip in the "Gallery" of the Atlas-B buoy system being “wet-tested” in preparation of the spring 2013 research cruise.

RDSEA is invited to attend the 2012 IOOS Summit:

Friday, December 28th, 2012
RDSEA attends 2012 IOOS Summit: Ocean observing has come a long way since the Ocean Sciences Decadal Committee met over a decade ago. Since then, our use of the ocean and coast and their vast resources has increased substantially – with increased shipping, fishing, offshore energy development and recreational boating.  That increased use has also spearheaded advances in observing systems.  The IOOS Summit is the exclamation point on the work preceding the event and will serve as an assembly of 200 representatives cross-sectioning the diverse and expansive ocean observing community regionally, nationally, and globally. Each day of the Summit will focus on a different theme:  A Decade of Progress (Day 1), Revisiting and Updating User Requirements (Day 2), Assessment of Existing Observing System Capabilities and Gaps (Day 3), and Integration Challenges/Opportunities and Vision for the Future (Day 4). For more information please see this link:   http://www.iooc.us/summit/ioos-summit/

RDSEA in Guyana, South America

Monday, October 8th, 2012
RDSEA teams with Olin Hydrographic Solutions, Miami, FL (olinhydrographic.com) on a full survey and site assessment of the Waini River in Guyana, South America. Moving raw natural resources from the Interior jungles of Guyana to market is a very challenging task. Understanding rivers and the coast line from the Interior provides an advantage for the planning and safe passage of barges and shipping traffic to the offshore environment of the region. Olin Hydrographic and RDSEA have been contracted to conduct bathymetry and ocean physics surveys at the mouth of the Waini River in western Guyana for this purpose. The initial bathymetric survey has been completed and over the course of a 12 month period beginning in June of 2012, wave measurements (height, speed, direction, and frequency), water level, current velocity and direction will be observed with final reporting due in the June/July time frame of 2013. A series of Teledyne RD Instruments ADCPs with waves technology have been deployed (sea floor mounted, looking up towards the surface) for three-month increments. The first recovery and data download is scheduled for Sept., 2012 with subsequent recoveries to follow. Please see the RDSEA "Gallery" (ADCP Deployments) for a pictorial review of this project.
