In this region, groundwater is almost exclusively obtainedfrom the thin alluvium in the main transverse valleys, which descend from theAndes in those sections where the valleys cross the northerly trending "centralvalley." Because of the steep groundwater gradients prevailing, the groundwaterresources are closely related to seasonal recharge. As the area is arid to semiaridand has been showing indications of increasing aridity over the past few years,water supply problems are proving to be a serious development constraint.Throughout the area, many examples of insufficient water supply may be encountered,and the problems of water use management and the utilization for industrialpurposes of supplies such as seawater, brines, and sewage are now being considered.

Algae and surf grass often are cover on the aboralsurface and are eaten on the oral surface. Strongylocentrotus purpuratus individualsshow no tendency to drop their cover at night and assume it again at daybreak.Individuals of this species are more extensively covered in areas of surge activitythan they are in tidepools. The materials most frequently used for cover also differin these two areas. The availability of drift materials is the most important factor indetermining the extent of covering and the types of covering materials held byStrongylocentrotus purpuratus.

Eightdifferent habitat types or zones were distinguished, each having a characteristicpolychaete fauna.The tidepools of rocky shores support up to 20 species, including the only tubeincubatingspirorbine found in Hawaii, Spirorbis marioni. Two of the three knownHawaiian chaetopterids, the large fan worm Sabel/astarte sanctijosephi, and 13serpulid species occur on reef platforms that lack lush coral growth. Four speciesof algae were found with associated polychaetes. The greatest number of specieswas associated with Dictyosphaeria cavernosa, which provides suitable habitats forcryptic and sessile organisms. Live coral heads and the subtidal, fringing reefsapparently have an impoverished tube-worm fauna. Spirobranchus giganteus is theonly living serpuline associated with live corals. The hard parts of mobile crustaceansand gastropods reveal a diverse invertebrate fauna, and the species compositionof the associated polychaetes reflects that of the surrounding environment.Boat harbors and lagoons have a typically rich fauna due to the introduction ofbenthic invertebrates on the bottoms of boats. Such habitats remain reservoirs ofintroduced species, which are important in the geographical distribution of tubeworms within the islands. Mercierella enigmatica and other euryhaline polychaetesare found in brackish waters. The unique anchialine pond systems of lava flowson Maui and Hawaii have discrete polychaete faunas and physical characteristicsinfluenced by a freshwater lens. Six serpulids and a sabellariid were dredged fromdepths of 200 to 600 meters off Oahu and Molokai.

Measurements, including radiantenergy transmission, plant nutrients, and chlorophylls, were made in the depthinterval 0-250 meters. The numerical vertical abundance, biomass, and the identityof phytoplankton, microzooplankton, bacteria, and fungi were determined. Adiscussion of the biological dynamics within this photic zone is based on theseobservations and on measurements of photosynthetic production, nitrogenfixation, and other microbial activities.
