Services | SCIENTIFIC DIVING

scientific diving.Normandeau has conducted extensive scientific diving programs in marine and inland waters throughout the United States for nearly 40 years.  Our scientific divers have collectively accumulated over 200 years of experience and have logged more than 10,000 underwater hours. Our dive procedures require that all divers conform to strict medical, safety, and training requirements; all our divers have both corporate and national diving certifications. Many of our divers hold advanced national certifications in the Advanced Diver, Rescue Diver, and Master Diver categories.  Additionally, all our divers and tenders have current certificates in National Safety Council First Aid, CPR, and oxygen First Aid. Dive personnel have worked in rigorous conditions including high currents, low visibility, and deep water and freezing temperatures.

Many of the environmental investigations conducted in coastal areas require underwater sampling of biota, sediments, water quality, or bottom conditions in ways that cannot be accomplished by remote sampling from the surface. Our team of SCUBA-certified divers has the ability to sample a full-range of environmental media including benthos, fish, sediments, and water. Our divers also have the ability to collect non-destructive data as well as photographic documentation of underwater conditions.  Diving operations conform to all pertinent safety standards, including strict adherence to OSHA regulations, Subpart T (Commercial Diving Standards), and the corporate Scientific Diving Safety Manual.  All equipment and employees are completely insured, including Harbor Workers Insurance and the MGL Endorsement.

diving.We also maintain over 15 boats to support nearly any type of diving operation.  All boats used in dive operations are equipped with communications, dive platforms, extensive first aid kits, and oxygen bottles with manual resuscitators. The Dive Operations program has its own compressor strictly for diving air, which is tested annually, and our Dive Operations Manager supervises our in-house diving equipment maintenance shop.  Examples of scientific dive surveys our team members have carried out include:

  • Underwater survey for early benthic phase lobster and quahogs for Massachusetts Coastal Zone Management
  • Multiple underwater surveys for submerged aquatic vegetation and eel grass throughout the East Coast
  • Underwater survey for eel grass and benthos for a beach nourishment project at Sconsett Beach located in Nantucket, Massachusetts
  • Extensive marine sampling for power plant studies in New Hampshire's nearshore waters (up to 100' depths) for the North Atlantic Energy Company (Seabrook Station, New Hampshire)
  • Transect surveys of biological and physical features, including photography and benthic sampling, for the HubLine gas pipeline project
  • Biological survey and bottom characterization for endangered mussels of a section of the Penobscot river in Maine, as part of the restoration planning for dam removal
  • Installation and video monitoring of acoustic fish deterrent studies of the Fitzpatrick power plant intake structures for New York Power Authority
  • Installation and inspection of a 600 foot fish barrier net for the power plant of Orange and Rockland Utility
  • Sediment stability tests and biological sampling, including underwater photography, transect surveys, benthic flora and fauna analysis of artificial reef placement for the Central Artery/Third Harbor Tunnel project
