This book was released on 2018 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Monthly water samples have been collected at sites around the Auckland refion since 1987. Long-term monitoring is important for identifying trends in water quality parameters that are highly variable between seasons and years. This report focuses on trends occuring between 2007 and 2016. During this time period we monitored 36 sites across seven areas: the east coast, Mahurangi Harbour, Waitematā Harbour, Tāmaki Strait, Tāmaki Estuary, Manukau Harbour and Kaipara Harbour. Our 10-year tyrend analysis showed that water quality has been largely improving across the region since 2007. There were some sites, however, where water quality is declining, mainly in the upper Waitematā Harbour. At these sites, nutrient and supspended sediment concentrations have been significantly increasing over the last five to 10 years, possibly due to an increase in urban development in these areas. We also found significant increasing trends in sea surface temperature across nearly all sites in the Kaipara, Manukau and Waitematā harbours. These increases are consistent with predicted patterns of sea surface temperature increase due to global climate change. Despite improving trends in water quality, many parameters still exceed water quality threshiolds for the Auickland region that are used to assess ecosystem health. Thresholds wetre exceeded most frequently in the Manukau and Kaipara harbours and for total suspended sediment, total organic nitrogen, and total nitrogen concentrations."--Executive summary.
