The coastal scenery of the Northeastern Adriatic sea is widely interested by caves and related coastal features, which are developed in correspondence of geological weaknesses of sea cliffs. We present the preliminary surveying of five partially submerged coastal caves cut in limestone cliffs, relating the dissolutionally widened vadose karst voids and the present- day forms. The analysis pointed out two well-defined morphological zones inside the caves. The boundary between the zones roughly coincides with the mean sea level. The submerged zone is mainly affected by abrasion processes on the bottom and the lateral walls, while the emerged zone is interested by karst processes and collapse of blocks from the roof. Their effects produce a bell-shaped cross-section, in which the submerged part of the caves is significantly larger than the emerged one. Considering the tectonic behaviour of the area inferred from literature the caves were flooded about 6 ka BP, when marine processes started to shape their submerged part. Our results allowed, in particular, to evaluate processes shaping the partially submerged coastal caves in the Northeastern Adriatic Sea after the marine transgression. Considering the very preliminary surveyed data, we suggest that the early phases of cave evolution was mainly dissolutionally-controlled and produced the widening of pre-existing joints or faults, as demonstrated by the occurrence of karst features in the upper part of the caves. Recent evolution is instead marine-controlled and the widening is mainly due to the overlapping of marine processes effects on karst voids, since they are closely related to the Late Holocene sea level rise


Quantitative hermeneutics: Counting forestructures on a path from W. M. Davis to the concept of multiple-permeability karst aquifers., 2015,

Hermeneutics is the theory of interpretation. One of its major components is recognizing prejudgments, or forestructures, that we bring to our objects of study. In this paper, we construct a historical narrative of the evolution of thinking about the role of caves in relation to groundwater flow in limestone, and we tabulate forestructures as they appear in the story. This account consists of three overlapping time periods: the before and after of an incident that repelled hydrogeologists and students of karst from each other in the middle of the 20th century; a period, up to around the turn of this century, when karst science and mainstream hydrogeology were on different tracks; and a period of convergence, now intertwining, beginning roughly in the last quarter of the 20th century. Two influential players in our story are M.K. Hubbert, whose introduction of the Eulerian perspective of flow was a force for divergence, and R.M. Garrels, whose founding of the field of sedimentary geochemistry was a force for convergence. Other key players include F.T. Mackenzie, J.E. Mylroie, V.T. Stringfield, the U.S. Geological Survey, the Bermuda Biological Station, and the Gerace Research Center in the Bahamas, along with the historical accounts of W.B. White. Our narrative ends with the broader acceptance of the concept of multiple-permeability karst aquifers. We flag in our construction a total of 43 forestructures distributed amongst the categories of hermeneutic theory: 14 in the category of preconceptions; 9 in goals; 14 in tools such as skills; and 6 in tools such as institutions. These counts are an example of the concept of social construction of statistics, and we discuss the implications in terms of the huge number of potential combinations of forestructures that could shape alternative historical narratives of this subject over this time frame.
