Final Report

Benthic community production and response to environmental forcing__WAMSI KMRP Project 2.2.3_Lowe et al 2016_Final

Aims

  • Understand the productivity and growth rates of communities of organisms on fringing reefs in the west Kimberley
  • Investigate the influence that ocean conditions (such as large tides) and seasonal changes (such as the monsoon) play on reef productivity rates
  • Trace the sources of material feeding reefs to their ocean or land origins

Proposed Methods

  • Record water motion and water quality on a fringing reef for short periods by deploying small, non-invasive oceanographic instruments
  • Collect water samples from atop fringing reefs and the surrounding ocean to test for nutrient and oxygen levels
  • Use small benthic chambers at some sites to directly measure production and respiration rates to compare with the water quality measurements
  • Conduct surveys of King Sound to monitor water quality over the year
  • Use computer simulations to understand water motion around reefs and the delivery of material from land

Project Duration -2013-2015

  • Field sampling will take place twice yearly, once in March and once in August, during both 2013 and 2014.  The first trip will be in April or May 2013.
  • Trips will be roughly 2 weeks in length, based out of the Kimberley Marine Research Station (KMRS) in Cygnet Bay

Geographic Range

  • Broad scale sampling in King Sound will take place at the stations shown above
  • Studies of the fringing reef platform will take place at Tallon Island

Outcomes

  • Demonstration of the uniqueness of Kimberley fringing reefs and comparison to other Australian reef systems
  • Key baseline information to support longer-term reef monitoring or management plans
  • Build capacity amongst Indigenous ranger groups through training of the key methodologies used in the research as well knowledge transfer of the key results.

Longer term goals beyond the life of the project

To provide scientific outcomes that inform and direct management plans for reef systems in the Kimberley region
