Up to an es­ti­mated 51m cu­bic me­tres of seabed ma­te­rial could be dredged to build and ex­pand ports in the reef. That is the equiv­a­lent of 49 times the vol­ume of New York City’s Em­pire State Build­ing. Dredg­ing is the re­moval of ma­te­rial from the seafloor to cre­ate har­bours and to deepen chan­nels so that large ships can ac­cess ports and ma­noeu­vre within them. Dredg­ing can ei­ther be cap­i­tal dredg­ing, which cre­ates new chan­nels and berths, or main­te­nance dredg­ing, which re­moves sed­i­ment from ex­ist­ing chan­nels and berths and typ­i­cally oc­curs ev­ery one to five years.
