All our data collection is supervised by a Certified Hydrographer. At our clients’ disposal is a wide array of hydrographic equipment, from single beam echosounders to dual head multibeam systems. Our hydrographic capabilities are further augmented by a full suite of state of the art positioning and motion compensation systems, and Sound Velocity and CTD units.
One of the key advantages of Alpine’s hydrographic services are the range of vessels we have at our disposal. Alpine has the right vessel for anything ranging from shallow ponds, lakes and inland rivers to estuaries, bays, harbors and open ocean. Our in-house fleet ranges from 10-foot skiffs to our 110-foot Research Vessel R/V Shearwater, capable of accommodating 20 people for surveying offshore on a 24-hour basis.
Alpine can take the raw hydrographic data and provide our clients with a wealth of information through a variety of industry standard and specialized hydrographic processing packages. This includes the ability to post process dual frequency GPS into high precision Post Processed Kinematic (PPK) data which can provide high accuracy tidal corrections in areas where tide gauges are not available or cannot be easily installed. Deliverables can, among many options, include contour charts, profiles, DTM’s, 3D images and/or volume/quantity calculations.
