Symbol Creation Service / German Bight.
« Last post by Eco_n on March 24, 2014, 03:53:40 pm »
I'd like to request the German Bight as an addition to the Image library using a perspective similar to the sea level rise graphic. And including most of the German (until the Dutch border more or less) & a good part of the Danish coastlines as well as the isle of helgoland.

thanks for your consideration,

Conceptual Diagrams Posted for Review / Sabkha
« Last post by peri on March 18, 2014, 01:19:40 am »
This diagram looks at the hydrochemistry that controls the distribution of three species of samphire across a coastal sabkha. I am struggling to get Adobe Illustrator to display the salt concentration of the groundwater the same way I have drawn it in my pencil drawing...

Soil sodicity is a problem for many areas of Australia subject of dryland salinity. The diagram highlights the chemistry of the problem.
Conceptual Diagrams Posted for Review / Use of potshard shelters for painted dragons

The diagram shows how to provide additional habitat for painted dragons along walking tracks in sandy habitats. The lizards need basking area, display area and shelter.
Thanks for all of the great resources. Your staff has already been extremely helpful to other inquiries I have had. I am writing to request the following symbols (images attached):

Yaupon holly, Ilex vomitoria

Beach vitex (chasteberry),Vitex rotundifolia

Red knot, Calidris canutus

Sonde being deployed for water quality monitoring

Weather monitoring station

Marsh bio-monitoring along transect

Longleaf pine, Pinus palustris

Thanks so much.

Symbol Creation Service / Periwinkle snails

Hi there,

Thank you so much for all of the great resources here! 

I'm writing with a request for 3 species of marine snails in the genus Littorina, and am including links to sites with good pictures (please let me know if these are insufficient!) of each.  The symbols are intended for use in a journal article and future conference/classroom presentations, though I am sure they will find much wider usage! 

1) Littorina littorea - Common periwinkle

2) Littorina saxatilis - Rough periwinkle

3) Littorina obtusata - Smooth/flat periwinkle

Thanks so much for considering making these!
Best wishes!
Symbol Creation Service / Polar Sea Ice
« Last post by Marie Auger-Methe on January 22, 2014, 12:37:17 pm »

Great website and tools!! I'm new to it, but so far I am really impressed!

I'd like a vector graphic of the polar marine ecosystem, with a focus on the sea ice. Similar to
but with a view from above, similar to
And with more sea ice.

In a perfect world it would have the coast, open water, and different type of ice, (pancake ice, annual ice, multiyear ice, ice berg, ice ridge, etc) that we could move in the graphic. This could serve as a basic map to add  arctic species ringed seals, polar bears, arctic char... and anthropogenic factors such as drilling. Most importantly it could be used to explain the impact of climate change on the Arctic sea ice habitat.

In the guidelines, it is asked to put photos as example. I don't have a photo that represent the sea ice habitat from above, but here are a few links to examples.The wikipedia page on sea ice has a few good examples: http://en.wikipedia.org/wiki/Sea_ice including a map that could serve as a good starting example.

Here is also an example of pancake ice: http://en.wikipedia.org/wiki/Pancake_ice

It would be great to have features such a seal breathing wholes (eg: http://neven1.typepad.com/blog/2012/02/february-2012-open-thread.html?cid=6a0133f03a1e37970b0167631feb8b970b)

Off course this is a lot to ask, so any map from above with sea ice would be a amazing start!

Many thanks!

The below five vector symbols are needed for educational touch screen programs that the Calvert Marine Museum is incorporating into its estuarine biology hall renovation. Any assistance you can give would be appreciated. We prefer the graphics to be in profile. Please feel free to contact us if you have any questions. Rachel Reese, Calvert Marine Museum, reeserl@co.cal.md.us or 410-326-2042, ext. 29.
