Clarity before a decision is made
Modeling conducted in offshore waters over a relatively large area is generally easier to stabilize.
Various tools and instruments are provided with specific types and specifications suitable for offshore waters. These tools and instruments are grouped based on the parameters to be measured, as follows:
Decision Supported
Define the approach, priorities, and actions for marine using traceable evidence.
Risk Controlled
Non-representative data, missed critical periods, and inefficient field cost.
Success Criteria
Quality-controlled data that meet the assessment objective and are analysis-ready.

Full technical basis and contextOpen this section to read the complete source technical narrative.
Modeling conducted in offshore waters over a relatively large area is generally easier to stabilize. However, the accuracy level of the developed model may vary. Reparameterization is required to achieve a reliable level of model precision. Therefore, field measurement data are essential for completing the model verification and validation process.
Various tools and instruments are provided with specific types and specifications suitable for offshore waters. These tools and instruments are grouped based on the parameters to be measured, as follows:
A seawater depth survey using portable survey equipment and large vessels, specifically for deep-water areas where strong acoustic signal performance and a wide sensor swath are required.
A seawater temperature survey by depth using portable survey equipment with temperature sensors that remain stable under changing conditions.
