Sand Island, Midway Atoll National Wildlife Refuge (MANWR), is home to 21% of all nesting black-footed albatross (Phoebastria nigripes) and 47% of all nesting Laysan albatross (P. immutabilis) worldwide. During the 2015–2016 nesting season predation and disturbance by non-native house mice (Mus musculus), here documented for the first time, resulted in 70 abandoned nests, 42 adult birds killed and 480 wounded. In the following nesting season the affected area increased, resulting in 242 dead adults, 1,218 injured birds and 994 abandoned nests. Mouse predation activities triggered a mouse control response to reduce mouse densities in the affected areas using multi-catch live traps, kill traps, and limited use of anticoagulant rodenticides in bait stations. In 2016–2017 we applied a pelleted cholecalciferol rodenticide, AGRID (Bell Laboratories, Madison, WI), at a rate of 20 kg/ha in all affected areas. The purpose of this study was to evaluate the efficacy of using AGRID to reduce mouse density and rate of mouse attacks on nesting albatrosses on Sand Island. Mouse attacks decreased and mouse abundance was reduced following rodenticide applications in the plots treated in December but changes in attack rates in the plots treated in January were not detectable and mouse abundance increased subsequent to treatment. The plots in the December treatments were much larger than those used in January and rainfall rate increased after December. A minimum size of treatment area may be necessary to achieve a reduction in injury rates in albatrosses. No deleterious effects were observed in non-target organisms. The casualties resulting from mouse predation (mostly Laysan albatross) represent a small proportion of the 360,000 pairs nesting on Sand Island. However, the risk to adult breeding albatrosses representing such a large fraction of the global population prompted the United States Fish & Wildlife Service to prioritise mouse control efforts.

2012
The Regional Meteorological Services Directors (RMSD) Meeting convened for its 14th session at the International Conference Centre in Majuro, Republic of the Marshall Islands from 9–12th August 2011. It was preceded by a Pacific Regional Meteorological Services Directors Workshop in Support of Climate Adaptation Planning in the Pacific Islands on 8th August. The objectives of the meeting were for participants to formulate and establish a clear understanding of the Pacific Meteorological Council (PMC), the Pacific Desk Partnership concept (since renamed as the Pacific Meteorological Desk Partnership, PMDP), and the Pacific Meteorological Strategic Plan (PMSP) (2012– 2015). A total of 54 participants attended the meeting. Primarily the participants were Meteorological Service Directors and representatives from American Samoa, Australia, Cook Islands, Federated States of Micronesia, Fiji, French Polynesia, Guam, Kiribati, New Caledonia, New Zealand, Palau, Papua New Guinea, Marshall Islands, Samoa, Solomon Islands, Tonga, Tuvalu, United States of America and Vanuatu. Representatives of the Finnish Meteorological Institute, SPREP, SPC, WMO, UNESCO-IOC, Institute for Global Environmental Strategies, University of Oklahoma, Pacific ENSO Applications Climate (PEAC) Centre (co-located at the University of Hawaii and the University of Guam) were also present
