The Archaeology of Underwater Caves

Authors:

Abstract and Figures

During the last 1 million years the global sea level fluctuated between 130m lower than at present to a few metres above present level due to changes in the volume of ice caps. During low sea levels Tertiary karsts were exposed on the continental shelf of the Mediterranean, new karstic solution occurred on others shelves, and new cliffs and caves were eroded on topography that is now submerged. When the coastal terrestrial water table was lowered subterranean drainage and karstic features were reworked to the new base level, with freshwater discharging onto the continental shelf. Caves eroded into cliffs by waves usually exploit weaknesses in the rock such as intersections of joints or fault planes, while karstic solution often follows the same weaknesses. Shoreline caves also form in igneous rock cliffs at joints and cooling cracks, as well as in dykes. Submerged caves often have composite origin, with erosion features near the seaward entrance, and solution or karstic features further back. Speleothems are common.

The karst of Mallorca Island (Balearic Archipelago, Western Mediterranean) is characterised by the occurrence of many coastal caves where phreatic speleothems accrete today, around conventional vadose-zone speleothems, in correspondence with the current sea level. Older deposits of this kind of carbonate precipitates have recorded ancient high and low sea stands by means of strictly horizontal alignments of the phreatic overgrowths on speleothems (POS) respectively located above and below present sea level. Mallorca has proved to be a good location for investigations on eustatic sea level changes because it is located far from former margins of the major ice-sheets and was only affected by a minor tectonic tilt since the end of marine oxygen isotope stage (OIS) 5e. A number of POS now located above and below present sea level have been dated by the U-series method using MC-ICPMS and TIMS. The obtained high-precision ages fall within a time interval ranging from 144,000 to 78,000 yr ago and provide constraints on sea level changes curve during the last interglaciation in Mallorca. Three high stands have been recognised corresponding to OIS 5e (138,000-128,500 and 122,000-110,000 yr) and OIS 5a (84,000-82,000 yr) separated by very fast sea-level falls. The resulting eustatic curve emphasizes the occurrence of marine level fluctuations greater than 18 m in amplitude within short time spans (< 5,000 yr).

While the sites of Forbes' Quarry and Devil's Tower are, respectively, unpromising and probably too dangerous for further excavation, there are several other sites on the Rock preserving evidence of Neanderthal activities. One, Ibex Cave, lies high up on the eastern face of the Rock, while four others lie to the southeast, close to the sea near 'Governor's Beach'. The present beach mainly consists of fine limestone blast debris from military tunnelling operations, but there are also cemented remnants of more ancient beaches which presumably accumulated during Oxygen Isotope Stage 5. The caves are named (from the south) Bennett's, Gorham's, Vanguard and Boat Hoist. Three of these caves (Ibex, Gorham's and Vanguard) have been excavated since 1994 as part of the Gibraltar Caves Project; some of the initial results of this work are presented below. Further details will appear in the proceedings of the Gibraltar conference held in August to celebrate the 150th anniversary of the finding of the Forbes' Quarry skull (Stringer et al. in preparation). The excavations at Gorham's and Vanguard Caves are already beginning to yield significant results relating to the palaeontological, archaeological and palaeoenvironmental aspects of the Neanderthals and their modern human successors. The integration of new AMS and other dating results with sediments analysis should help us compare the sequences in both caves and to provide frameworks for situating human behaviour. For example, it would be interesting to know whether changes in sea level and resulting reconfiguration of the coastal plain were major factors responsbile in the Neanderthal exploitation of highly local raw materials for tool-making and the frequency of gathering of marine/estuarine foods. Using this information and comparing the archaeological evidence from the Middle and Upper Palaeolithic levels at the sites will help to place the Gibraltar finds in their European and Mediterranean contexts.

In Mediterranean karsts, the Messinian salinity crisis induced first a deepening of the karst systems, then a flooding after the Pliocene transgression, and finally a reorganization of the drains after this base level rise. This reorganization mainly corresponds to the development of phreatic lifts: the chimney-shafts and the vauclusian springs. Such a per ascensum speleogenesis appears with a base level rise, which is caused by eustatism, by fluvial aggradation or valley infilling, or by continental subsidence. Consequently, we explain the origin of most of the deep phreatic cave systems (which are not hypogenic) by a base level rise, which flooded the deep karst, producing phreatic lifts connected to vauclusian springs.

Archaeological evidence on the island of Lefkas, in large areas with terra rossa on the island of Corfu, and on heavily eroded surfaces of the adjacent islets of Dhiapl, Mathraki, and Othonoi, to the northwest of Corfu, indicates substantial human occupation at least during the Middle Palaeolithic and the terminal Upper Palaeolithic. The distribution strongly indicates major lowering of sea level, and a land bridge between the Greek mainland and the island during Wurm I and III at least. -from Author

The African continent represents a significant lacuna in respect of offshore prehistoric archaeological research. A recent survey of the scientific literature has indicated that with the exception of one South African project, Operation ‘Zembe’, no archaeological work pertaining to prehistoric periods has been undertaken to date anywhere offshore of the coasts of sub-Saharan Africa. Recent developments, however, have stimulated further plans to extend research into this field in the region. In the following, motivations for conducting sub-sea prehistoric archaeology in Africa are discussed. This is followed by a description of methodology. By describing aspects of research design and strategy, an opportunity exists to compare African prehistoric submarine archaeology with work undertaken elsewhere in the world.

The Verlorenvlei is a coastal lake which in the past acted as a magnet for prehistoric settlement. Study of the modern shellfish populations illustrates patterning which can be shown to have been influential in locating prehistoric camps. The spatial and temporal patterns in shell midden accumulations reflect changes in both local and regional settlement strategies. -Authors
