I did a screen clip of the page at ctbto.org\/specials\/vdec\/\u00a0 You can see that it is overlaying text over text.\u00a0 I highlighted the overlay and could sort of read it.\u00a0 I found the “here” to find the VDEC application form.\u00a0 I changed the magnification of the page but that just makes it worse.\u00a0 That clip below is 100%<\/div>\n
<\/div>\n
I am going through most of the sensor networks on the Internet and just starting on the IRIS.edu microbarographs and related infrasound networks.\u00a0 I have gathered notes on infrasound for some time, but only just have time now to check the models and data and networks.\u00a0 If someone will tell me what signatures CTBTO is trying to identify and quantify, I can add that to my list of global sensor network requirements.<\/div>\n
<\/div>\n
In a paper I am reading this morning, Measuring Infrasound from the Maritime Environment by Doug Grimmett, Randall Plate and Jason Goad<\/a>, they filter an injected signal and it made me think of CTBTO, then they mentioned CTBTO again, I decided to try once more to look for the data.<\/div>\n
<\/div>\n
I kept hearing about CTBTO having a network, but could never find if it was publicly available.\u00a0 Maybe this scrambled page is why I could not find it.<\/div>\n
<\/div>\n
Anyway, maybe you can see what is going on with that page.\u00a0 Overall, CTBTO.org has poor text color contrast.\u00a0 And hard to read text variations and size combinations (large and small text sized mixed, too many font variations).\u00a0 You can do anything you want on the Internet, but best practices aim for clarity and simplicity.\u00a0 Please do not use ALL CAPS anywhere (your left panel and headers and footers).\u00a0 And please please don’t use pastel text.<\/div>\n
<\/div>\n
Your “text only” is pretty horrible.\u00a0 If you cannot do it nicely, best to not bother.\u00a0 \u00a0If it was for accessible to blind readers, you missed very badly.\u00a0 It does not allow selecting some of the text, and the links don’t work consistently.\u00a0 I see the entire Internet and every conceivable thing, and I would not comment if it were not really exceptionally bad.\u00a0 And probably not that hard to fix.\u00a0 Most website owners and builders on the Internet never check their sites, and never use any of the forms and tools themselves enough to see if they work at all.\u00a0 Overall, most forms on the Internet do not work the way people hope they will.\u00a0 Most of the sites just keep adding things, they never clean up, index, curate their own materials.\u00a0 It is a mess. But, even if I am supposed to write the policies, I just let people do whatever they want.\u00a0 You would think large corporations and international organizations would have more pride. But, like I said, almost all the website owners never check their sites from the outside, if at all.<\/div>\n
<\/div>\n
I cannot tell, but I\u00a0 think CTBTO does not include the gravitational sensor arrays.\u00a0 That marine infrasound absolutely requires inertial measurements at high frequencies (oversampling and to correlate with higher audio and electromagnetic frequencies).\u00a0 I will see what alternatives there might be.\u00a0 So much has changed in just the last year with the precipitous drop in the cost of sensors and on-board processors – across all sensor types.<\/div>\n
<\/div>\n
I will check to see how the earth-quake early warning groups are using infrasound.\u00a0 And all the low frequency electromagnetic groups. They all overlap in the range from nanoHertz to GigaHertz.\u00a0 That is what makes it interesting.<\/div>\n
