1:25 Decision to stop 'calling the bar' extremely dangerous

Bay of Plenty Regional Council's decision to stop "calling the bar" will cost lives, says Whakatāne Sport Fishing Club president Heyden Johnston.

Regional council harbourmaster Jon Peters said skippers are best placed to decide whether to cross the bar on the river entrance.  

But fishing club president Johnston, who has been on the water in Whakatāne for 40 years, is concerned.

He says the regional council is relinquishing liability when it should be leading the way with a safety first approach.

1:35 The potential for more species to inhabit Antarctica, new research

Researchers at the University of Otago have discovered an increase in pockets of open water on the continent, which could mean coastal plants and animals could eventually establish there.

They were there to try and understand where open water might allow coastal species to settle in the future, but say the dramatic increases they saw in these pockets was unexpected.

Research Fellow Dr Grant Duffy led the team, and says they're not sure exact what is driving the increase, but that the ecological implications could be huge.

Senior author on the study Professor Ceridwen Fraser from the university's Department of Marine Science speaks to Jesse.
