The 2 500 metre isobath chapter 4

THE 2,500 METRE ISOBATH (CHAPTER 4)

Harald Brekke


The role of the 2 500 m isobath

The role of the 2,500 m isobath

  • The fixed points comprising the line of the outer limits of the continental shelf on the sea-bed, drawn in accordance with paragraph 4 (a) (i ) and (ii), either shall not exceed 350 nautical miles from the baselines ….. or shall not exceed 100 nautical miles from the 2,500 metre isobath, which is a line connecting the depth of 2,500 metres” (Paragraph 5, article 76)


Relevant bathymetric data

Relevant bathymetric data

Primary data:

- Single-beam echo soundings- Multi-beam echo soundings

Complementary data:

- Bathymetric side-scan sonar measurements

- Interferometric side-scan sonar measurements

- Seismic reflection-derived bathymetric measurements

(See 4.2.1 - 2)


Ice covered areas

Ice-covered areas

  • In special cases such as in ice-covered areas the CLCS may regard also the following as primary data:

    • Seismic reflection-derived bathymetric measurements

    • Interferometric side-scan sonar measurements (See 4.2.3)


Selection of points along 2 500 m isobath for delineating the 100 m maximum limit

Selection of points along 2,500 m isobath for delineating the 100 M maximum limit

  • The 2,500 m isobath may occur as multiple repetitions along the continental margin

  • Use the first 2,500 m isobath from the baselines that conforms to the general configuration of the continental margin, unless there is evidence to the contrary (See 4.4.2)
