The observed regional variability in the coastal response to ENSO has important implications for coastal planning and adaptation measures across the Pacific, particularly in light of projected future changes in ENSO amplitude and flavour. I wanted a Tetrapod in my bedroom, but the real one is too big, and if I hit it in the night, it would hurt, he laughed, noting that he has a personal taste that favors non-organic materials and sterilized design. Source data are provided with this paper. However, at the same time, nutrient salts supplied from rivers and abundant light in the shallow waters support high primary productivity. Young, A.
