The Republic of the Marshall Islands: State of the Environment (SOE) Report 2016
Available Online
2016
The 2016 State of Environment (SOE) Report for the Republic of Marshall Islands (RMI) updates the 1992 SOE report. It uses the DPSIR model (Drivers, Pressures, State, Impact and Response) and aims to:| Document the key drivers and pressures behind the changing environment.| Assess the RMI environment since 1992, using the best available information on the state of RMI’s environment in seven key themes: Atmosphere and Climate, Land, Marine, Biodiversity, Culture and Heritage, Built Environment and Nuclear Legacy.| Document the impacts of environmental changes on the society, economy and environment from changes in the state of the environment.| Document current responses to protect and better manage RMI’s natural resources.| Provide recommendations for RMI to address key challenges and link them to actions in the National Environmental Management Strategy (NEMS) and other key policy documents. This report is comprised of three discussions: 1. Drivers and Pressures in Marshall Islands: A summary of the main points discussed in the Pressures and Drivers section of the report. 2.The State of RMI’s Environment and Impacts on the Society, Economy and Environment: Key findings for each of the seven themes. 3. Responses and Recommendations – Challenges in Moving from Policy to Action: This presents key responses, opportunities, challenges and recommendations.

Microplastics are widespread in the natural environment and present numerous ecological threats. While the ultimate fate of marine microplastics are not well known, it is hypothesized that the deep sea is the nal sink for this anthropogenic contaminant. This study provides a quanti cation and characterisation of microplastic pollution ingested by benthic macroinvertebrates with different feeding modes (Ophiomusium lymani, Hymenaster pellucidus and Colus jeffreysianus) and in adjacent deep water> 2200 m, in the Rockall Trough, Northeast Atlantic Ocean. Despite the remote location, microplastic bres were identi ed in deep-sea water at a concentration of 70.8 particles m 3, comparable to that in surface waters. Of the invertebrates examined (n ¼ 66), 48% ingested microplastics with quantities enumerated comparable to coastal species. The number of ingested microplastics differed signi cantly between species and generalized linear modelling identi ed that the number of microplastics ingested for a given tissue mass was related to species and not organism feeding mode or the length or overall weight of the individual. Deep-sea microplastics were visually highly degraded with surface areas more than double that of pristine particles. The identi cation of synthetic polymers with densities greater and less than sea water along with comparable quantities to the upper ocean indicates processes of vertical re-distribution. This study presents the rst snapshot of deep ocean microplastics and the quanti cationofmicroplasticpollutionintheRockallTrough.Additionalsamplingthroughoutthedeepseaisrequiredtoassesslevelsofmicroplasticpollution,verticaltransportationandsequestration,which have the potential to impact the largest global ecosystem.
