The Nga Motu Marine Reserve Society is opposed to the Trans-Tasman Resources Limited (TTR) application to undertake iron sand mining in the South Taranaki Bight. The unprecedented scale of the sand mining proposal may be a marine engineering first, but also puts the marine ecosystem at great risk. All benthic organisms within the mined area (65km2, 2-3 times the area of urban New Plymouth) will be destroyed over a 20 year period. Sand mining will create a plume of sediment roughly 50km in length and 20km in width (approximately 2-3 times the area of the Egmont National Park). Over a substantial area of the plume, increased suspended sediment load will affect light penetration, resulting in reduced visibility (affecting reactive distance of fish and aquatic birds) and reduced primary production by phytoplankton (the base of the marine food web). In addition to producing a gigantic sediment plume, re-deposition of mined sand will smother benthic communities and have a ‘choking’ effect on those organisms living within the water column.
