Marine Nature and Plastic

In 1990 David Bellamy stated: Ninety Mile Beach, clean sand washed by purest sea and Parengarenga Harbour, ... possibly the purest and most unpolluted on the earth. Fast forward to 2019 and the map below shows the density of plastic within the moana that surrounds us. Each dot represents 20kg of plastic and the whiter the area the more dense the plastic is.

Last year's reports stated NZ oceans are the most dangerous in the world for seabirds eating plastic waste and Oriental Bay has some of the world's worst plastic pollution.

The aim of this project is to photograph and document examples of how plastic affects the marine environment in New Zealand waters. We can see from the chart below the top 10 plastics that pollute the moana, yet our obs here already show that it is plastic from fishing, such and lines and bouys that do the most damage that we have photographed and documented so far. What observation of plastic affecting marine nature have you observed? Please add to the project page.

Effects of Plastic on Land

Currently, New Zealand is rated the 10th worst nation for creating urban waste.

If we look at our umbrella project Nature and Plastic it shows we have far more NZ Marine Nature and Plastic obs than for this project.

But what of the plastic waste that never reaches the ocean and is instead confined to land? Are plastics a danger to terrestrial animals too? Keep an eye out for plastic that is impacting on our terrestrial nature.

It's nest building time and some birds build nests using plastic. What are other things that terrestrial critters do with plastic?

NZ Shell Photo ID - Now Live - Includes Barnacles and Echinoderms

Officially launched! The NZ shell photo ID guide that our user @indeynz (Andrew) has spent the last two years coding for his website mollusca.co.nz is now finally live!

Following the prompts or looking at photos, you can use it to narrow down what the shell is that you have found, as long as the shell is commonly encountered, either at the moana or on the whenua.

As a lot of people who are new to identifying mollusa can sometimes think that a barnacle or a kina is a mollusca, both of these phyla are also a part of the Identify guide.

Here is the URL
NZ Mollusca Identify by Shape or Form

Background to this guide.
Indeynz lives up my way which means we often get together to roam the moana. About 4 years ago, I started hinting there should be a shell ID guide (similar to the NZ Birds Online) to help people like me find an ID. Naturally I got told, "Oh no! That will be too hard - I am never going to do that!"

For those of you who know me, that answer was not an option. So every now and again, for the next 2 years I would hint about the great idea for the guide and he finally caved, so he could come over to my whare more often. I realised after a few times, it was because I had faster internet connections than he usually had, so he could update his laptop, as long as he was working on the guide.

A few months ago, we were at a stage that it could go live, so I contacted some of you to test it - and your input was very valuable and appreciated by both of us :D

Disclaimer from indeynz who is standing here as I type this (and his laptop updates):
This is still a work in progress. Any feedback on the guide would be most welcome. You can send me a message through here, or contact me through my website NZ Mollusca

So now the next time you go to the moana and find a shell that you do not know, have a go with this guide!

Enjoy :D

Quadrants Sorted

Working in quadrants means that it is easier to keep track of what is where. These have been worked out by easy access points.

Not all areas have actually been explored as some are too thick to get through, so who knows what goodies are here :)

Just realised Q17 has some nasty invasive tree in the middle and I don't know what it is as haven't been in there, but seeing as the Neighbourhood project is starting on Sat for a week, I will hold off exploring until then - have to help Tai Tokerau do well :D

Haere Ra Wade Doak

One of the first to advocate for the protection of the marine environment in the 1960s and the reason for the Poor Knights Marine Reserve being formed, Wade, who was sometimes compared to Jacques Cousteau has passed at 79 years of age.

Our world is a much richer place because he came.

Moe mai ra e te rangatira.

Hunt for Syndesmis kurakaikina - New Species of Flatworm

If you eat kina then the next time you are going to have a feed, get your trusty camera ready then look for the new species of flatworm that has been formally described called Syndesmis kurakaikina and lives in the gut of kina.

It is tiny and is circled in photo B. Photo C shows it and the bar represents 1mm

Image taken from the Full Article

Happy eating and happy hunting!
