have been trained in plankton ID work <strong>and</strong> over three years of samples analysed.<br />

ZBD2010-42 Marine <strong>Environment</strong>al Monitoring Programme.<br />

This project continues from ZBD2008-14. A starting point to the assessment <strong>and</strong> reporting of<br />

broad-scale changes in New Zeal<strong>and</strong>’s marine environment is to define basic criteria <strong>and</strong> locate all<br />

existing <strong>and</strong> past time series of marine environmental data to improve awareness <strong>and</strong> access to<br />

these data. After this, these data can be evaluated as to their fitness-for-purpose for contributing<br />

towards a national Marine <strong>Environment</strong>al Monitoring Programme (MEMP). To date an online<br />

catalogue has been designed <strong>and</strong> a portal to this is available at http:\geodata.govt.nz.<br />

Questionnaires were developed to determine what marine environmental time series data were<br />

available within New Zeal<strong>and</strong>. Information to date gives us 131 databases, 50% of these are listed<br />

as having ongoing funding (although not necessarily for all locations), <strong>and</strong> another 19% are listed<br />

as likely to continue. Over 70% are publically available. Most cover more than one location,<br />

although this is dependent on how the databases are constructed, e.g., DOC at present has a<br />

separate database for each marine reserve, while regional councils tend to have separate databases<br />

for different subjects (e.g., contaminant monitoring, ecological monitoring). Around 95estuaries<br />

<strong>and</strong> harbours are being sampled, which is not surprising given that the majority of the information<br />

comes from Regional Councils (Figure 1). There are 78 coastal locations <strong>and</strong> 33 marine reserves.<br />

The second phase, determining fitness-for-purpose, was begun at a workshop held at NIWA on<br />

11th June (see objective 3). Priority variables for inclusion in a national monitoring programme<br />

have been identified from responses to a questionnaire sent to scientific experts <strong>and</strong> central <strong>and</strong><br />

regional government departments involved in monitoring <strong>and</strong>/or reporting. Core reference sites<br />

<strong>and</strong> major gaps in the spatial network are presently being determined <strong>and</strong> the requirements for<br />

spatial <strong>and</strong> temporal sampling determined. The project is due to be completed by June 2013.<br />

EMERGING ISSUES<br />

Monitoring coastal waters <strong>and</strong> New Zeal<strong>and</strong>’s oceans to report on a national scale remains a major gap<br />

There is little longterm commitment to direct monitoring the marine environment<br />

11.3.7. Scientific Objective 7. Identifying threats <strong>and</strong> impacts to<br />

biodiversity <strong>and</strong> ecosystem functioning<br />

Many marine ecosystems in New Zeal<strong>and</strong> have been modified in some way through the harvesting of<br />

marine biota, the selective reduction of certain species <strong>and</strong> size/age classes, modification of food<br />

webs, including the detrital components <strong>and</strong> habitat destruction. Benthic communities including<br />

seamount communities, volcanic vent communities, bryozoans, corals, hydroids <strong>and</strong> sponges are<br />

vulnerable to human disturbance. The mechanical disturbance of marine habitats that occurs with<br />

some activities such as trawling, dredging, dumping, <strong>and</strong> oil, gas <strong>and</strong> mineral exploration <strong>and</strong><br />

extraction; can substantially change the structure <strong>and</strong> composition of benthic communities. The<br />
