Scientia Marina, 1999 Changes in nutrients, chlorophyll and zooplankton were followed for 11 d in a basin of the Straits of Magellan (Paso Ancho), characterized by a homogeneous water column during a spring event defined by a drastic change in wind stress and direction ...

Early indicators of tidal ecosystem shifts in estuaries [PDF]
, 2023 Forecasting transitions between tidal ecosystem states, such as between bare tidal flats and vegetated marshes, is crucial because it may imply the irreversible loss of valuable ecosystem services.

Limnology and Oceanography Bulletin, EarlyView.Abstract Statistical analysis is a cornerstone of scientific research, yet young researchers in aquatic sciences often struggle when analyses begin without a clearly defined research question or a solid understanding of the data structure. This disconnect between data collection and analytical decision‐making recurrently drives unreliable findings ...

State of Our Estuaries 2009 [PDF]
, 2009 The 2009 State of the Estuaries Report describes the status and trends of 12 primary indicators tracked by PREP. For each key indicator, the report provides the monitoring question and answer, PREP management goal, information on relevance, and an ...

Saved or starved? The importance of sediment management in determining the future response of estuaries and deltas. [PDF]
, 2023 The primary mechanism which forms and maintains estuary and delta morphology and elevation is sedimentation. Sediment deposited annually may offset elevation loss due to relative sea-level rise (SLR).

Limnology and Oceanography: Methods, EarlyView.Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ$$ {a}_p\left ...

Evaluating indicators of ecological health for estuaries in southwest Australia [PDF]
, 2001 A broad range of environmental indicators were evaluated to determine their suitability for describing the early onset of nutrient enrichment in south-west Australian estuaries.

Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?
Limnology and Oceanography: Methods, EarlyView.Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Contribution of ultrafine particles to alkalinity in a limestone‐treated waterbody
Limnology and Oceanography: Methods, EarlyView.Abstract While it is well recognized that suspended particles can bias titration‐based total alkalinity (TA), whether addition of minerals for alkalinity enhancement introduces systematic TA artifacts remains poorly quantified. To address this gap, we quantified the contribution of ultrafine particles (< 0.2 μm) to TA titration introduced by limestone (

Limnology and Oceanography: Methods, EarlyView.Abstract Fluorometric enzyme assays are a tool for determining potential enzyme activity in soils. A wide array of methodological approaches is adopted by different studies, making comparisons difficult. An important consideration is whether assay conditions replicate the environment of the samples or optimize potential enzyme activity.
