The importance of each of these oceanographic parameters for mine warfare operations vary, in some cases significantly, between different water depths (Table 3-1~. For example, in many coastal environments, wind-generated currents are of little importance in the surf zone as they are generally overwhelmed by wave-induced currents, whereas in very shallow water (VSW)

VSW = Very Shallow Water SW = Shallow Water H = High, a parameter that is essential for mine warfare operations in this depth zone; M = Medium, a parameter that is useful for mine warfare operations in this depth zone; L = Low, a parameter that is of little use for mine warfare operations in this depth zone; N/A = A parameter that is not applicable or not measurable in this depth zone.

developing better in situ sampling systems for measurement of tactically significant oceanographic and meteorological parameters. As discussed previously, the need to improve environmental databases and interactive data visualization capabilities is particularly important for mine warfare planning and operations.

used to estimate coverage for acoustic minesweeping equipment. At present, no algorithms exist to recalculate these parameters according to environmental changes, but future algorithms may take into account acoustic water depth, seawater physical properties, wind speed, and bottom composition.

Acoustic imagery mosaics provide accurate estimates of bottom roughness and clutter density (Figure 3-5) , and are source data for determining MIW doctrinal seafloor classifications.

These features are likely to have resulted from seafloor release of hydrocarbon gases. FIGURE 3-4 A pair of acoustic imagery mosaics collected four days apart.

MWPs are digitally output to the METOC officer. Oceanographic/Environmental Summary OESs provide baseline oceanographic information on specific geographic areas.

In addition, ONR provides technical advice to the operational branches of the Navy through the Chief of Naval Operations and the Secretary of the Navy (ONR, 1999~. The science and technology arm of ONR maintains close links with the oceanographic research and technical development communities by supporting proposals that will benefit naval operations (ONR, 1999~.
