That blue hole is 1. deep resurgence pool, notably in jamaica and florida, that may have a blue color due to the presence of algae. also a deep submarine cave of the bahamas. the latter type are large flooded shafts cut into the limestones of the shallow reefs and lagoon floors. many are 100 m in diameter and some are 100 m deep. opening from the shafts are flooded cave passages at various depths, some of which have been explored subhorizontally for more than 1 km. their origins are complex. extensive stalagmite deposits show that large old caves were drained when sea-levels were low during the pleistocene (when water was held in the ice sheets). they are now being modified by marine dissolution, notably at the interface between fresh and salt waters (sea littoral zone) and by powerful tidal flows between connected holes [9]. 2. (jamaican.) a major emergence where water (artesian spring) rises from below without great turbulence. 3. (bahamas.) a drowned solution sinkhole [10]. 4. caribbean expression for a major quiet up-welling karst spring inland or along the coast. the blue color is due to the scattering of sunlight by water molecules, although in some cases it may be attributed to the presence of calcareous algae [20]. synonyms: (french.) source bleue (jura), bleu-fon (south of france); (german.) blaue grotto; (greek.) galapo speleo. see also boiling spring.?

Hydrology of autogenic percolation systems in some tropical karst outcrops, West Malaysia
Abstract:
This paper reports on the flow regimes of underground seepages in three tower-karst outcrops and in the Setul Boundary Range, West Malaysia. Groundwater movement in the tower-karst hills, which comprise very pure, massive marbles, is confined to vertical and subvertical joints. Although flow is primarily diffuse and the discharges of the majority of seepages correlate most closely with rainfall in antecedent periods of 1-16 days or more, some stormflow occurs along conduits in the upper parts of these aquifers. Many of these conduits appear to peter out at depth into tight rock fractures, thereby forming funnel-shaped underground reservoirs which serve to moderate discharge variations. In contrast, the limestones of the Setul Boundary Range are less pure and retain much of their original bedding. The presence of near-horizontal bedding plane fractures favours lateral groundwater movement and the development of integrated drainage networks within the rock. Compared with the tower-karst caves, seepage rates are generally higher and more responsive to short-term variations in rainfall. The marked difference in topography between the tower-karst hills and the Setul Boundary Range is largely attributable to the contrasted geohydrological properties of the limestones
