Kelp Patch-Specific Characteristics Limit Detection Capability of Rapid Survey Method for Determining Canopy Biomass Using an Unmanned Aerial Vehicle

open access: yesFrontiers in Environmental Science, 2022
Kelp forests dominate autotrophic biomass and primary productivity of approximately 30,000 to 60,000 km of shallow temperate and Arctic rocky reef coastline globally and contribute significantly to carbon cycling in the coastal ocean.

Functional Insights into the Kelp Microbiome from Metagenome-Assembled Genomes

open access: yesmSystems, 2022
Eukaryotic organisms evolved in a microbial world and often have intimate associations with diverse bacterial groups. Kelp, brown macroalgae in the order Laminariales, play a vital role in coastal ecosystems, yet we know little about the functional role ...

Kelps on demand: Closed‐system protocols for culturing large bull kelp sporophytes for research and restoration

open access: yesJournal of Phycology, 2023
AbstractCulturing kelps for commercial, conservation, and scientific purposes is becoming increasingly widespread. However, kelp aquaculture methods are typically designed for ocean‐based farms, and these methods may not be applicable for smaller scale cultivation efforts common in research and restoration.

Marine heat wave and multiple stressors tip bull kelp forest to sea urchin barrens. [PDF]

open access: yesSci Rep, 2019
AbstractExtreme climatic events have recently impacted marine ecosystems around the world, including foundation species such as corals and kelps. Here, we describe the rapid climate-driven catastrophic shift in 2014 from a previously robust kelp forest to unproductive large scale urchin barrens in northern California.

Large-scale shift in the structure of a kelp forest ecosystem co-occurs with an epizootic and marine heatwave

open access: yesCommunications Biology, 2021
Meredith McPherson et al. use a 34-year time series of satellite and in situ derived data to study bull kelp forests of northern California and demonstrate the ecosystem shifts following a marine heatwave event between 2014 and 2016.

Comparing the Use of Red-Edge and Near-Infrared Wavelength Ranges for Detecting Submerged Kelp Canopy

open access: yesRemote Sensing, 2022
Kelp forests are commonly classified within remote sensing imagery by contrasting the high reflectance in the near-infrared spectral region of kelp canopy floating at the surface with the low reflectance in the same spectral region of water.

Energetic context determines the effects of multiple upwelling-associated stressors on sea urchin performance

open access: yesScientific Reports, 2021
Globally, kelp forests are threatened by multiple stressors, including increasing grazing by sea urchins. With coastal upwelling predicted to increase in intensity and duration in the future, understanding whether kelp forest and urchin barren urchins ...

Interactive effects of temperature and nitrogen on the physiology of kelps (Nereocystis luetkeana and Saccharina latissima)

open access: yesFrontiers in Marine Science, 2023
Kelp forest declines have been linked to warming ocean temperatures worldwide. Ocean warming rarely occurs in isolation, so multiple stressor studies are necessary to understand the physiological responses of kelp to climate change.

Ground into Place

open access: yesPacific Arts, 2022
As a Trawlwoolway artist from Trouwunna, also known as Tasmania, I seek to challenge Western constructs of Australian colonial histories. I work to liberate Palawa cultural objects from their hidden status, often combining them with Western manufactured ...

A Review of the Opportunities and Challenges for Using Remote Sensing for Management of Surface-Canopy Forming Kelps

open access: yesFrontiers in Marine Science, 2021
Surface-canopy forming kelps provide the foundation for ecosystems that are ecologically, culturally, and economically important. However, these kelp forests are naturally dynamic systems that are also threatened by a range of global and local pressures.
