The effects of terrestrial sediment inputs on ecosystem functions in seagrass meadows and unvegetated sediments
… and long-term accumulations increase sediment mud content (particles < 63 µm), both of which could have significant consequences on ecosystem functioning. Understanding how ecosystem functioning may respond to environmental change is vital to estuary management. In this thesis, I investigated …

Denitrification response to nutrient enrichment in New Zealand estuaries
… loads, resulting in habitats dominated by muddy organic-rich sediments. Nutrient processing and denitrification in estuarine sediments represent important ecosystem functions regenerating nutrients for primary producers, and regulating the ability to remove excess terrestrially derived …

Changes in benthic ecosystem properties and functions across sedimentary gradients in estuaries
… natural gradients of silt and clay (hereafter mud) to determine the effects of habitat change associated with chronic sediment loading on the structure and functioning of benthic communities. There were significant declines in measures of macrofaunal diversity and the maximum densities of key …

Mangrove ecosystem dynamics and clearance impacts
… of transition to sandflat conditions (decline in mud content, change in macrofaunal communities) than larger mechanical clearances. However, sediment characteristics and macrofaunal communities remained more comparable to intact mangrove than sandflat ecosystems over 3 years following mangrove …

Origin of brecciated intervals and petrophysical analyses: the Three Forks Formation, Williston Basin, North Dakota, U.S.A.
… four lithofacies: (1) a green to gray or red mudstone, (2) a disrupted to mottled, interbedded silty dolostone and mudstone, (3) a silty, tan dolostone, (4) and an interbedded silty dolostone and mudstone. The middle Three Forks consists of a deepening upwards sequence capped by a basin wide …

Tīmata whakaora, kickstarting recovery - Using bivalves to bioremediate degraded estuarine sediments
… ecosystem function proxies, reducing sediment mud content, increasing oxygen consumption, and stimulating ammonium flux, even when survival was low, compared to unaided recovery. In contrast, M. liliana showed limited direct effects on the measured ecosystem functions and the co-addition of …

Detecting anthropogenic impacts on estuarine benthic communities
… Zealand. Both land-derived stressors (sediment mud content and total sediment nitrogen and phosphorus content) and natural environmental variables (sea surface temperature, Southern Oscillation Index, and wind-wave exposure) were important predictors of compositional turnover, reflecting a …
