Oceanography Department

At AEX Group, we understand that environmental conditions are a critical factor for the success of farming centers. That’s why our Oceanography Department conducts thorough preliminary studies to assess whether a site meets the necessary climatic and oceanographic conditions—minimizing risks and ensuring the stability of aquaculture operations.

SERVICES

Wave Study

The wave study is based on the capture of waves generated by local winds, instrumentally measured by ADCP equipment, focusing on wave height and period conditions from a characteristic direction. This study defines the operational conditions of an aquaculture concession based on prevailing and dominant wave conditions.

Additionally, extreme events are projected probabilistically using long-term wave data obtained through hindcasting methodology, aligned with characteristic return periods based on the engineering structure’s lifespan.

This study adheres to the guidelines of D.S. 320 (Subpesca), RES. EX. 1821 (Subpesca), and Publication 3201 (SHOA).

Current Study

The current study involves characterizing fluid movement throughout the water column, parameterized by velocity and direction over time at a fixed point (Eulerian approach), with data captured using ADCP equipment. These studies may serve different purposes—engineering or environmental—based on statistical and spectral analysis.

Additionally, extreme events are projected probabilistically using long-term wind data (from in situ and/or satellite sources), considering characteristic return periods based on the engineering structure’s lifespan.

This study follows the guidelines set by RES. EX. 1821 (Subpesca) and Publication 3201 (SHOA).

Wind Study

The wind study involves characterizing the air masses affecting a concession area, measured using an instrument called an anemometer. This device records wind speed and direction over time to define the air flow conditions impacting the site.

This study is conducted in accordance with the guidelines set by D.S. 320 (Subpesca), RES. EX. 1821 (Subpesca), and Publication 3201 (SHOA).

Exploratory Bathymetric Study

The single-beam bathymetric study service allows for the identification of seabed depth using an instrument that emits an acoustic pulse, which bounces off the seafloor. The return signal’s response time is then interpreted as depth. This bathymetric study is essential for defining the engineering design of mooring systems and serves as a critical input for numerical models of environmental forcing.

The study follows the guidelines established in RES. EX. 1821 (Subpesca) and the hydrographic instructions of SHOA.
