Sandcastle

On an empty beach
in sunlight
I built my castle
the wind was my architect
together we sculpted
soft curves from the dunes
I found ribbons of seaweed
sprawling like handwriting
in the tideline of debris
washed from the sea of knowledge
with these I garlanded the walls

that giggled stories about crabby hermits
and boring barnacles
someone has spilt black
tar on my castle
ink black sticky stains
that burn where they touch me
that burn

Effects of Rising Ocean Acidification on Fisheries in Spotlight

A reef fish that can’t find its way home and whose erratic behaviour constantly puts it in danger might make a nice premise for a children’s movie, but oceans filled with Dory’s could spell disaster for their survival.

Higher atmospheric carbon dioxide levels means more is being absorbed in seawater, with some young fish’s nervous systems being affected.

Notwithstanding the wonderful diversity of marine wildlife around our shores, with 130 species commercially fished in New Zealand and worth $1.2 billion annually, finding out what’s in store for them in a warming world is important.

If snapper and others start showing Dory traits fishery’s could be affected.

With a budget of nearly $5 million over 4 years researchers at Niwa, Cawthron Institute in Nelson, University of Auckland, and Otago University under the Carim (Coastal Acidification: Rate, Impact and Management) programme will be looking at affects on phytoplankton, aquaculture species paua and greenshell mussels, and young snapper.

They’ll also incorporate data from long term monitoring already going on at 14 diverse sites around the coastline—part of the New Zealand Ocean...
