Oceanographic Survey

Oceanographic surveys can provide a range of information on the physical properties of the water column and how these can change over varying timescales.

Such information (including flow speed/direction, wave climate, water quality and suspended sediment concentration) can often be the primary drivers for physical changes and/or alterations to an environment over time.

At ABPmer we deliver bespoke oceanographic services to meet a range of client needs. Where ocean characteristics (hydrodynamic, wave climate or sediment transportation) are required over a large area, numerical models can be created by our hydrodynamic modellers. In this case oceanographic data will be acquired by our surveyors at specific areas of interest to calibrate the results of the numerical model.

Current and wave monitoring

We deploy seabed frames with self-recording instruments to capture tidal currents and/or wave parameters for fixed time periods ranging from individual spring & neap tidal cycles to full seasonal or year-long campaigns. We also conduct vessel-based Acoustic Doppler Current Profiler (ADCP) transect surveys over single or multiple tidal cycles to obtain high-resolution flow speed and direction measurements across a section of estuary or seabed.

Seabed sampling

We conduct singular or multiple site campaigns to collect seabed surface material throughout estuarine and nearshore areas. This may be for a general site classification and characterisation or in preparation for detailed physical and/or chemical laboratory analysis.

Tidal analysis and numerical modelling

Using datasets collected during current monitoring we undertake harmonic analysis to determine hydrodynamic characteristics at any given site, using these to provide predictions for a future period depending on client requirements. Such datasets can be used to calibrate high-resolution numerical models created by ABPmer’s in-house hydrodynamic modellers.

Water quality observations

We deploy a range of instrumentation to measure multiple water quality parameters, obtained either at the near-bed via seabed frame deployments, or as vertical profiles throughout the water column. We can also conduct specific water quality monitoring depending on client requirements.

Water sampling

We conduct detailed water sampling throughout the water column to determine total suspended solids in our accredited laboratory, ultimately aiding calibration of acoustic monitoring measurements and current monitoring programmes.
