Greek Shark Logbook

Welcome to the Greek Shark Logbook, your premier resource for tracking and understanding shark activity in the waters of Greece.

Our mission is simple yet profound: to gather, compile, and analyze data from various sources, including social media and news reports, to document sightings of sharks, whether they are swimming or caught during fishing activities.

Here's how we make it happen:

Data Gathering: We scour social media platforms and news outlets to collect firsthand accounts and documented sightings of sharks across Greek waters. Each sighting is meticulously logged into our database, providing valuable insights into shark populations and behaviors.
Annual Reports: At the dawn of each new year, we consolidate the wealth of data gathered throughout the previous year into comprehensive PDF reports. These reports offer a detailed overview of shark sightings, trends, and patterns observed in Greek waters, serving as invaluable resources for researchers, conservationists, and enthusiasts alike. Moreover, these reports are made available for purchase, allowing individuals to delve into the fascinating world of Greek shark activity firsthand.
Integration with Sharkbook.ai: Our collaboration with Sharkbook.ai enables seamless integration of our data, particularly focusing on the identification of specific shark species. Through this integration, sightings of the Great White Shark (Carcharodon carcharias), Grey Nurse Shark (Carcharias taurus), Basking Shark (Cetorhinus maximus), Nursehound Shark (Scyliorhinus stellaris), and Blacktip Reef Shark (Carcharhinus melanopterus) are meticulously analyzed. By harnessing advanced algorithms and AI technology, Sharkbook.ai enhances our efforts to identify individual sharks within these species, contributing to a deeper understanding of their movements and behaviors. This collaboration not only enriches our database but also empowers conservation initiatives aimed at protecting these remarkable creatures and their habitats. Together, we pave the way for a harmonious coexistence between humans and the diverse shark species inhabiting Greek waters.

Join us on our journey to unlock the mysteries of Greece's shark population. Together, we can shed light on their importance in our marine ecosystems and work towards their protection and conservation for generations to come.
