The central Pacific Ocean with its many low lying islands and atolls is under threat from sea level rise and increased storm activity. Here, we illustrate how increasing frequency and severity of large scale storm events associated with global climat

Quantifying the ecological importance of individual habitats to highly mobile animals is challenging because patterns of habitat reliance for these taxa are complex and difficult to observe. We investigated the importance of lagoons to the manta ray,

Anthropogenic lead (Pb) inputs to the atmosphere increased greatly over the past century and now dominate Pb supply to the oceans. However, the Pb content of sediments across the equatorial Pacific region is relatively unknown, and data exist only fo

Namuka Reef is a broad fringing reef flat situated immediately adjacent to the populous and heavily industrialized areas surrounding Suva Harbor, Fiji Islands. Reef flat sediments are mainly very poorly to moderately sorted carbonate gravels and sand

Palmyra Atoll has four partially isolated lagoons up to 50 m in depth, each with complex and variable bottom topographies. Measurements of depth, temperature, salinity, turbidity and dissolved oxygen (DO) revealed a well-mixed shallow surface layer (

The recognition of littoral sediment cells has proven valuable to coastal zone management in many areas of the world because it emphasises that sediment transport and deposition relate to physical processes rather than to administrative boundaries an

Reef islands of Palmyra Atoll in the northern Line Islands, equatorial Pacific Ocean, underwent mainly minor natural changes in shape and size between 1874 and 1940. Many major changes occurred between 1940 and 1945 when military construction created

Virgulinella fragilis can be mainly observed in different, separated, oxygen-depleted and sulfide-enriched environments around the world and seems to be well adapted to such extreme habitats. Dispersal mechanisms behind this geographical distribution

Carbonate sediments are the sole indigenous source of aggregate for infrastructure development on many Pacific islands, and their importance has increased markedly since the middle of the last century. Biogenic gravel and sand are extracted in many p
