• Nutrient Cycling and Primary Productivity

  Tidal currents facilitate the exchange of nutrients between estuarine and coastal waters. Flood tides transport nutrients from the ocean into marshes and creeks, fueling primary productivity by phytoplankton and marsh grasses. Ebb tides export organic matter and detritus, supporting food webs in offshore waters. Alterations in tidal flow patterns can disrupt this nutrient cycling, potentially leading to algal blooms or oxygen depletion. Changes in salinity due to altered freshwater input can impact nutrient availability and primary production.

• Species Dispersal and Connectivity

  Tidal currents serve as vectors for the dispersal of larval organisms and the movement of migratory species. Many marine invertebrates and fish rely on tidal currents to transport their planktonic larvae to suitable settlement habitats. Migratory fish, such as striped bass, use tidal creeks as pathways to access spawning grounds. Modifications to tidal flow regimes, such as the construction of dams or causeways, can impede species dispersal and reduce connectivity between habitats. Disrupted connectivity can impact genetic diversity and population resilience.
