Automatic estimation of eelgrass cover using seafloor images

This research assesses various methods to monitor eelgrass populations along Canada's eastern coasts. This is done by providing image data to deep learning models to estimate the percentage cover of eelgrass from these models. The dataset comprises ocean

Japanese eelgrass (Z. japonica) monitoring

, 2008
Japanese Eelgrass (Zostera japonica) has successfully invaded the Pacific Coast of North America. Since its introduction into Washington in 1957 it has moved up to Boundary Bay, Nanaimo, and Ucluelet. Thought as beneficial for a fisheries perspective, Z.

Nitrogen Cycling in Widgeongrass and Eelgrass Beds in the Lower Chesapeake Bay

Nitrogen
Eelgrass (Zostera marina) loss occurs worldwide due to increasing water temperatures and decreasing water quality. In the U.S., widgeongrass (Ruppia maritima), a more heat-tolerant seagrass species, is replacing eelgrass in certain areas.

Survival strategies of eelgrass in reduced light

, 2008
Light reduction due to anthropogenic impacts is the most widespread cause of worldwide decline of eelgrass, an ecologically important marine angiosperm whose role in supporting overall coastal ecosystem productivity has been widely recognized ...

The Population Genetics of Morro Bay Eelgrass (Zostera marina)

, 2017
Seagrass populations are in decline worldwide. Zostera marina (eelgrass), one of California’s native seagrasses, is no exception to this trend. In the last 8 years, Morro Bay, California has lost 95% of its eelgrass.

Use of Landsat Imagery Time-Series and Random Forests Classifier to Reconstruct Eelgrass Bed Distribution Maps in Eeyou Istchee

Remote Sensing
The eastern coastline of James Bay is known to have been home to sizeable eelgrass beds (Zostera marina L.) which thrived in the bay’s shallow, subarctic waters.

The effects of mesograzers in eelgrass communities [PDF]

, 2007
Seegrasgemeinschaften gehören hinsichtlich ihres Nutzens für die Allgemeinheit zu den wertvollsten Ökosystemen überhaupt. Sie bieten Lebensraum für eine diverse Gemeinschaft von Invertebraten und Fischen, dienen als Habitat und Futterquelle, sowie als Kinderstube für kommerziel wichtige Arten. Die Fähigkeit von Seegraswiesen Sediment und Nährstoffe aus

Eelgrass disease dynamics: An experimental analysis of the eelgrass - Labyrinthula zosterae interaction

, 2018
Infectious diseases in the marine realm may have severe ecologic and socio-economic implications. This thesis addresses disease in the foundation species Zostera marina, commonly known as eelgrass. In the 1930s ‘wasting disease’ hit trans-Atlantic Zostera marina L. (eelgrass) populations, provoking the biggest ever reported seagrass die-off.

Biophysical model of eelgrass and water quality in Coos Bay, OR shows greater mitigation potential for ocean acidification than hypoxia

Frontiers in Marine Science
Seagrass beds provide important ecosystem services and are valued, in part, for their potential to mediate stressors such as ocean acidification and hypoxia (OAH) for sensitive species.
