The natural conditions of many of the oceans’ benthic habitats have been increasingly impacted by the expansion of human occupation on earth. Today, the waste and pollution generated by humans are being concentrated in the oceans and the input of CO2 into the atmosphere is causing global warming along with sea-level rise, which results in acidification of seawater and shifting seafloor conditions. Just in the last hundred years plastics have increased in unbelievable magnitudes and is now a major contributor to ocean pollution. The cumulative effect of hydrocarbon production to make plastic and the proliferation of the material is substantially impacting the oceans. Accelerated marine traffic from merchant shipping to recreational boating has increased the potential for oil spills and other toxic materials along with lost shipping containers, seafloor disturbances from anchoring and mooring, all brought about in the past 20 years by “globalization” of trade. Tourism, especially eco-tourism is stressing some of the ocean’s most critical habitats. In addition, the global demand for more of the earth’s natural resources such as seabed minerals, fish, and energy along with the desires for renewable energy resources such as wind and tidal power are impacting critical seafloor habitats. In the last year, the outbreak of the Covid-19 pandemic is generating tremendously large amounts of waste in the form of rubber gloves, masks, and other personal protective equipment (PPE), detritus that are making their way to the oceans. This onslaught will have significant deleterious effects on many marine benthic habitats.

We believe that this is the time to address the mounting problem of pollution and waste impacts on seafloor habitats. Although a single volume cannot focus on all of the mentioned problems, attention needs to be drawn to selected impacts through knowledgeable scientific seafloor mapping investigations using the most up-to-date mapping technologies and data processing software packages. We propose a special issue of Continental Shelf Research that will present mapping case histories and topical investigations that will highlight what is known today about the alterations of marine benthic habitats and what is to come in the future. Below we list potential topics along with some suggested paper titles that can reasonably be addressed in regard to mapping efforts that illustrate some of the anthropogenic impacts to the marine benthic substrate and benthic habitats. We are soliciting contributions from the GeoHab community and have already received interest from many potential contributors and anticipate approximately 18 months of time needed to produce a comprehensive special volume from the time of announcing the effort.
