Autonomous Vertical

Profiling Systems

InterOcean's Vertical Profiling

System (VPS) autonomously collects and telemeters high resolution time- series vertical profile data, providing a complete spectrum of oceanographic parameters in real-time. Each unit collects detailed vertical profiles for the target depth range on a regular automated cycle, providing time- series data sets for long-term deploy- ments. Each VPS consists of four major subsystems: winch system,

S4VP-3 sensor platform, subsurface buoy with system controller, and bot- tom mounting system.

SHOALS-1000T

SHOALS-1000T is a complete air- borne laser bathymetry survey instru- ment for shallow water and coastal regions. Coupled with a fully inte- grated flight planning and data pro- cessing software subsystem,

SHOALS-1000T is a total coastal survey management solution, designed for surveys in shallow water, with land/water interface, hazardous areas, and areas requiring rapid envi- ronmental assessment. It features area coverage rates as high as 70 sq. km/hr and collects data with a high- accuracy laser, mounted in the aircraft floor.

WinchDAC Winch

Monitoring and Data

Logging System

The WinchDAC monitoring sys- tem displays line tension, payout, and speed for multi-winch installations through a central operator computer interface. Signals from count and force sensors mounted on each winch are captured and converted into engi- neering units by an LCI processor, and the resulting data moves through a serial interface to a central PC with optional touch-screen display. The program has the ability to log and summarize data for each winch and cast, replay the time history plot for any parameter from past casts on a second screen, calibrate winch ten- sion and count sensors directly from the central computer, and allow oper- ators to customize the display to their specific requirements.

GAVIA - The Great

Northern Diver

The GAVIA autonomous underwa- ter vehicle (AUV) is a fully modular, small torpedo shaped vehicle capable of diving to 2,000 m. It is an autonomous system in a small pack- age that can be configured for a wide range of research, surveying or moni- toring tasks. The system features fully shrouded propeller and control sur- faces, over-the-horizon operation and servicing, expandable control soft- ware and chart-based graphical mis- sion planning. Benefits of modulari- ty are numerous and include rapid battery replacement, reduced mainte- nance cost and customization options.
