Ship density

PMAR-MASE

1 month: Jan 2015

logarithm of # ships present

on average at any one time

per square degree

Sources:

Sat-AIS + LRIT

Sat-AIS: 17 satellites from

Norwegian Coastal Adm. / FFI,

exactEarth, SpaceQuest,

Orbcomm / LuxSpace.

LRIT: from Flags using the EU LRIT

Data Centre via EMSA.

Based on ship tracks, i.e. the density is

not biased by the irregular occurrence of

the messages

EEZ boundaries (in red) are taken from an

open source map and for orientation only,

The ship density map (previous slide) shows:

• Main shipping routes as straight lines

• Activity around ports as red points

• Cloudy structures are for the most part fishing activity

(EEZ boundaries are taken from an open source map

and for orientation only, not authoritative)

Split by speed, to better map activities

• Fast moving ships (> 6.5 knots)

• Slow moving ships (< 6.5 knots)

Slow-moving ships only (< 6.5 knots)

(from satellite AIS + LRIT)

Some things to note:

• Over the months, fishing activity moving from south to north

• Heavy presence in Eastern part of Madagascar EEZ in the 2014 months

• Empty holes in Nov 2014 related to EEZ boundaries and Agalega Island

• Activity in Somalia EEZ in April 2015 (only)
