Shipping in the Aegean Sea
 Mediterranean Sea supports between 4-18% of the worlds
species
 Aegean Sea is an area of the Mediterranean which carries
high biological importance, due to the relatively low coastal
development.
 However, the preservation of this ecosystem is being left
largely to chance, with few protection measures in place. If
damage to the area increases or a major event the results
could be severe.

Shipping in the Aegean Sea
 Hundreds of cargo, tanker and passenger ships pass through
the Aegean Sea every day. The potential impacts of
shipping, commercial and recreational, are vast.
 Ships can affect marine biota in the following ways:
–
–
–
–
–
–
–
–
Underwater noise created by ships
Anchoring
Grounding
Direct collisions
Carrying invasive species
Operational oil discharges
Accidental oil discharges
Thermal Discharges

Project Motivation
 The Aegean Sea lacks efficient mechanisms to manage,
monitor and regulate ship traffic conditions.
 To decrease the chance of ecological disturbance events,
strict shipping lanes must be established and enforced.

Project Motivation
 Over the last few months, the marine and GIS teams from
Archipelagos have been working on a major shipping project.
 From November 12, 2009 to April 29, 2010, data on all of
the tankers and cargos that travelled between Samos,
Ikaria, Mykonos, Andros, and Nisos Evia were recorded.

The data was received from www.marinetraffic.com and
www.mariweb.gr, which track and record data from shipping
vessels.

Project Goals: Details
1. Create a Graphical User Interface (GUI) [done]
2. Place ship markers at arbitrary pixel locations on the map [done]
3. Parse the AIS database and plot each ship at a given time interval on the
map [done]

Project Goals: Details
4. Create a function to assign a scalar “risk value” for each ship given
certain database attributes for each ship (cargo, size, proximity to
coast and other ships, flag, etc) [In Progress]
5. Create a visual identifier to show the risk of each ship (change
color, display numeric label, etc) [done]

Project Goals
7. Create a function to assess the risk of a particular map pixel
location based on the number and proximity of ships within a given
radius and proximity to land [In Progress]
8. Create a map view which shows risky areas in red and less risky
areas in green/blue. This “risk density map [In Progress]

Approach: About the Input
 Huge data collections
 Good facilities to collect real time data
 Accurate information to predict the trend of routes and risk
management
 Used dataset provided by International Maritime Information
Systems (IMIS)
– Covers 2 days worth of AIS messages
 Challenges with the IMIS dataset:
– Raw data - not decoded
– Not well managed
 Redundant data (3x redundant)
– Database not as supportive for GIS development

12
Approach: About the Input
 Automatic Identification System (AIS)
– is an automated tracking system used on ships and by Vessel Traffic
Services (VTS) for identifying and locating vessels by electronically
exchanging data with other nearby ships and VTS stations.
– AIS information supplements marine radar, which continues to be the
primary method of collision avoidance for water transport.
 Types of Info. Encapsulated within the Messages
– Static [MMSI number, IMO number, callsign, ship name and
type, dimension]
– Dynamic [position, time, speed, heading, course over ground,
rate of turn, navigational status]
– Trajectory-based [destination, estimated time of arrival,
draught]
