www.sea-technology.com November 2017 / st 43 Canada Funds Study of Human Impact on Ocean Canada is implementing a $50.8 million Coastal Environmental Base- line Program to help assess the impacts of human activities on the country's marine ecosystems. During the coming years, scientists from Fisheries and Oceans Canada and community partners will collect comprehensive baseline data in six areas of the country where there is existing or potential increasing vessel traffic: Port of Vancouver, BC; Port of Prince Rupert, BC; Lower St. Lawrence Estuary, QC; Port of Saint John, NB; and Placentia Bay, NL. The sixth area will be located in the Arctic. Studying the current state of these areas will enable better detection of changes in the environment and im- provement of understanding of the ef- fects of human activity on the marine environment over time. The data col- lected from this program will be used when making decisions that could im- pact sensitive marine habitat and spe- cies. $2.1 Million for Tech To Monitor Giant Kelp Farms One of the most productive organ- isms on Earth, giant kelp depends on nutrients from the surrounding water column to maintain its photosynthetic apparatus and maximize growth rates, which can reach 1.5 ft. a day. Such prolific growth makes giant kelp an excellent candidate to replace corn as a biofuel. While this species naturally grows close to shore, it easily could be farmed in deeper waters. This is the fo- cus of a new $22 million U.S. Depart- ment of Energy project called Macroal- gae Research Inspiring Novel Energy Resources (MARINER), which seeks to develop offshore kelp farms to produce kelp biomass as a novel energy source. A team of UC Santa Barbara sci- entists will receive $2.1 million over three years from the U.S. Department of Energy's Advanced Research Proj- ects Agency-Energy to develop and test technologies that monitor large- scale giant kelp farms. The team will combine and refine existing technol- ogy to enable farm managers to care- fully monitor kelp beds and maximize yields. Catalina Sea Ranch has also re- ceived MARINER funding of $450,000 as a prime contractor. The company is also the subcontractor on an additional $1,815,529 award to conduct research at its offshore aquaculture facility for developing a seaweed industry for the U.S. The global commercial seaweeds market was valued at more than $10 billion in 2015 and is expected to ex- ceed $22 billion by 2024. Underwater Metal Detectors For Multiple Applications Every day, bodies of water are used for recreational purposes, to supply food and drinking water, to help stock natural resource supplies, and to pro- vide a natural habitat for marine life. Sometimes valued possessions from people become lost in these waters, or these waters are used to discard evi- dence from a crime scene. An example of a multipurpose un- derwater metal detector is JW Fish- ers SAR-1, designed for use by public safety dive teams, law enforcement agencies and military units that need to locate metal objects in underwater environments with poor visibility. The Miramar Police Department Dive Re- covery Team utilizes the JW Fishers Pulse 8X with a 10-in. coil. TerraAquat- ic Inc., specializing in hydrographic surveying, also recently purchased a handheld underwater metal detector from JW Fishers. QARTOD Updates Manual for Ocean Optics Observations QC The U.S. Integrated Ocean Observ- ing System (IOOS) Quality Assurance/ Quality Control of Real-Time Oceano- graphic Data (QARTOD) Project has updated the "Manual for Real-Time Quality Control of Ocean Optics Ob- servations," which includes variables such as in-water and above-water ra- diance and irradiance, beam attenua- tion, PAR (photosynthetically available radiation) and CDOM (colored dis- solved organic matter). The content for this and other QA- RTOD data quality control manuals originates with a diverse community of ocean-observing experts with exten- sive knowledge of the variable being addressed.
