Specialists in marine offshore, nearshore & freshwater surveying

Alpine Ocean Seismic Survey, Inc. (Alpine), founded in 1957 and a Gardline Company since 2009, provides industry and government with the technical expertise to plan, acquire and interpret scientific data from marine and freshwater environments. Company capabilities include geophysical, geotechnical, hydrographic, oceanographic, environmental and positioning services. Since our founding by a group of Lamont Doherty scientists over 50 years ago, Alpine has worked on more than 3,000 marine survey projects worldwide. Alpine maintains its company headquarters in Norwood, New Jersey, shares a regional office with the Gardline Group in Houston, and can draw on Gardline’s global presence, extensive resources and over 2,000 employees.

Alpine’s specialty is planning and implementing multidiscipline surveys in inland, estuarine, coastal and offshore environments. We support design engineers, environmental consultants, numerical modelers, regulatory agencies, and project owners. Our strength is the ability and willingness to provide our clients with a turnkey service, anywhere on the globe. Alpine’s involvement often starts at the planning/permitting stages and, depending on the project type, runs through the desk top study, field acquisition, delivery of reports and high quality marine cadastre data, construction monitoring and ongoing maintenance and inspection phases. This capability is critical to insure accountability, proper data integration and cross checking throughout a project’s life cycle.

Alpine owns several vessels ranging from smaller trailered outboard and inboard shallow water survey launches to the 110-foot long RV Shearwater which is capable of 24-hour operations and accommodates 20 people. Alpine also operates an extensive inventory of in-house equipment.

Of key importance to many of our clients is Alpine’s reputation of being able to quickly and efficiently mobilize third party vessels, whether it be in our own backyard or in some remote region of the world. The flexibility to either use our own vessels, or mobilize third party options, provides our clients with the most efficient and cost effective approach to conducting a survey, no matter what the conditions or geographic location.
