Case No. #1583
Croatia, Korčula Island Coast: 'Deep Sea Silence' Rapid Weathering Incident
Summary
In the early hours of July 12, 2023, a fishing vessel operating off the coast of Korčula Island, Croatia, discovered severe damage to its retrieved gillnet. Metal components of the net had corroded at an unusual rate, and synthetic fibers were significantly embrittled. As authorities began their investigation, it was found that similar fishing gear damage and electronic equipment malfunctions had been reported in this area in the past. An unmanned submersible identified a WWI-era shipwreck with abnormal corrosion on the seabed, confirming acoustic attenuation and rapid material structural degradation at specific points. This suggests an unknown physical phenomenon that absorbs specific frequency sound energy and destabilizes material structures. Authorities have yet to identify the cause of the phenomenon and continue to monitor the affected area.
Details
In the early hours of July 12, 2023, the fishing vessel 'Star of the Adriatic,' operating off the coast of Korčula Island, Croatia, retrieved its gillnet to find severe damage. Metal components had corroded at an unusually rapid rate, and synthetic fibers were significantly embrittled. The captain attributed the extreme corrosion to the net contacting the seabed, but the extent of the damage was far beyond what typical friction or currents would cause.
The captain testified that similar incidents had occurred in the same waters previously, and authorities became aware of a specific area known among some fishermen as the 'Silent Waters.' A review of historical nautical charts and records by authorities revealed several reports of fishing gear damage and electronic equipment failures in this area since the 1980s. These reports consistently concentrated within a specific range of latitudes and longitudes.
On August 5, 2023, authorities deployed an unmanned submersible to commence a seabed survey of the designated area. At a depth of approximately 80 meters, the submersible discovered the remains of a shipwreck, believed to be from World War I. The vessel's hull showed signs of weathering at a rate far exceeding normal corrosion, appearing as if centuries had passed. Particularly peculiar was the concentrated corrosion on specific parts of the hull, with surrounding seabed sediment pulverized into a sandy consistency.
The submersible's acoustic sensors recorded an abnormal phenomenon at the target location, where ambient sounds were severely attenuated. Furthermore, high-precision metal detectors and electromagnetic wave measuring devices onboard the submersible frequently malfunctioned, yielding inconsistent data. This raised the possibility of some unknown force interfering with the instruments' readings.
On August 15, 2023, a specialized dive team was deployed. They reported that upon approaching the target area, their instruments temporarily malfunctioned, and their sense of balance underwater was significantly impaired. One team member testified, "It felt like being in a void that sucked away sound." Samples retrieved by the divers exhibited a peculiar property, showing visible degradation within just a few hours.
Authorities conclude that an unknown physical phenomenon exists in this area, capable of absorbing specific frequency acoustic energy while simultaneously destabilizing the material structures of its surroundings. This phenomenon is not widespread but occurs locally within an extremely confined space. Its generation mechanism, periodicity, and extent of material impact remain largely unknown. Authorities have placed the designated area under strict surveillance, awaiting further investigative opportunities.

- August 18, 2023Retrieved samples confirmed to be undergoing continuous degradation. Initial analysis identifies an unexplained physical phenomenon.
Witness Testimony
Fisherman A (Captain)When I pulled up the net, I couldn't believe my eyes. The metal was completely rotten, and the rope crumbled at a touch. It's not the first time this has happened. They say there are 'Silent Waters' off this coast.
Diver BThe moment we approached the target, audio cut out from my headset, and my sense of balance was lost. The instruments temporarily read zero. It felt like being in a void that sucked away sound. A powerful sense of unease.
Kyu's Analysis
Unexplained energy interference is the cause. Is this phenomenon a sign of another deep-sea event? Recording continues.
