Actual hydrometric measurements taken within the cave systems provide information on the extent, interaction, and seasonal variability of flooding in the caverns.<\/p>\n<p>Knowledge of the water level patterns allows explorations to be planned safely around periods caves are known to flood.<\/p>\n<p>Another importance of gathering water level data is to add to the more-in-depth examination of these under-explored cave environments. The resulting data sheds some light on the complex hydrodynamic life in the caves and provides a model for cave geometry and hydroactivity.<\/p>\n<p>Speleo (caving) expeditions to the deepest caves in the world are technically complicated and understandably carry many risks. Each data mining effort requires the organization of at least two expeditions: one for instrument installation and a second for data retrieval.<\/p>\n<p><\/p>\n<p>There are not only dangers to the lives of the cavers venturing to these depths and less explored areas, the loss or damage to expensive equipment is also a considerable issue.<\/p>\n<p>Due to the magnitude of flooding and water entering the caves, equipment like Leveloggers can be damaged from excess pressure and become dislodged from their anchorage. There is also the chance of instrument vandalism.<\/p>\n<p>After prolonged periods of deployment, it may be challenging to relocate the Leveloggers due to changes in the caverns over time, the small size of the instruments in the vast caves, and environmental and human factors\u2014such as extreme fatigue!<\/p>\n<p>Due to all the risks and complexities, any new data collected and every piece of information gathered is a significant success in itself!<\/p>\n<h3>Expedition to Sarma Cave<\/h3>\n<p class=\"p1\"><span class=\"s1\">In 2018, through Solinst&#8217;s Lithuanian representative Bernardas Pauk\u0161tys, Solinst donated two sets of dataloggers to the Lithuanian Speleologists&#8217; Club Aenigma (<a href=\"http:\/\/www.speleo.lt\" target=\"_blank\" rel=\"noopener noreferrer\">www.speleo.lt<\/a>).<\/span><\/p>\n<p>In December 2018, Lithuanian cavers joined an international expedition to the&nbsp;Arabika mountain plateau in Gagra District, Georgia (<a href=\"https:\/\/www.rgo.ru\/en\/article\/cave-was-previously-considered-third-depth-may-be-deepest-world\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.rgo.ru\/en\/article\/cave-was-previously-considered-third-depth-may-be-deepest-world<\/a>).
