As shown in Chapter 4, the scientific demand for deep submergence assets is, at present, not being adequately met. Part of this problem can be traced to the inadequacy of the number and capabilities of existing assets to perform the type of scientific effort associated with deep submergence 105

In particular, the current management system does not always ensure a match between the requirements of federally funded projects and the appropriate deep submergence assets. Modification of existing assets and construction of new assets to alleviate this problem would represent a significant capital investment and would likely engender additional demand for operating funds.

If additional funds were to be made available, excess demand could also be addressed by leasing non-NDSF assets. There appear to be situations, however, in which deep submergence scientific goals cannot be met by NDSF assets but can be met by noniThe submersibles used to support deep ocean research are similar to those discussed in two recent reports Enabling Ocean Research in the 21st Century: Implementation of a Network of Ocean Observatories (NRC, 2003a)

For example, limitations on the viewing capability of Alvin and its capability to achieve neutral buoyancy multiple times during a single dive make it less suited for certain types of midwater biological research than certain non-NDSF assets. For this reason, arguments favoring the full utilization of NDSF assets have the unintended consequence of restricting the scope of deep submergence science.

This increase should have a modest impact if it is anticipated and the overall budget is increased incrementally in preparation for the construction and operation of a new ROV. One justification for adding a new ROV system to the NDSF asset pool is to provide even greater geographic range to the growing number of ocean scientists seeking access to deep submergence assets.

Detailed descriptions of specific sites or work in the water column benefit from the direct human observation allowed by HOVs. Despite rapid and impressive growth in the capabilities of unoccupied vehicles (both remotely operated and autonomous)

Given the technical and cost uncertainties, and that the scientific justification for conducting HOV operations at depths greater than 4,500m appears to be incremental (i.e., it represents promising but logical extensions of work supported at shallower depths) , it is not clear that significant additional resources (i.e., in excess of those needed to fully upgrade the current NDSF HOV capability;, as discussed in Chapter 4)

As such, the discussions in this report are designed to inform this question and are not intended to provide an exhaustive account of all researchrelated activities carried out at depth or a complete account of all the potential assets that exist. The discussion of assets in this report is limited therefore to those that establish whether adequate deep submergence vehicles exist within or outside the National Deep Submergence Facility.
