  1. TIDES More graphics... Tidal bulge friction.tif Tidal inequality.tif moonecliptic.tif baytide.tif
  2. WAVES Some of the more useful drawings and charts. Most, if not all, are from Bascom. Let me know if you'd like others. Swell speed table.tif refraction14.tif breakcirc.tif Development fetch.tif Wave period spectrum.tif Refraction on shore.tif Development fetch.tif barformation.tif Summer winter beach.tif Developed sea table.tif Sea wave spectrum.tif
  3. I have an extensive slide show, but it would make little sense standing alone. No written handouts. The reference I used most and would recommend was Waves and Beaches, by Willard Bascom, revised edition 1980. It can be found through Abe or Amazon, typically as a library discard. Waves, by Fredric Raichlen, 2013, MIT Press, is concise and worthwhile. Past that, I stole from every source available.
  4. It looked to me that he'd plotted the tide stations around here, but not the current stations. He's from Seattle, and presumably hasn't put the time into it. A similar source is anyTide, an iOs/Android app with tides/currents around the UK.
  5. There's one other source you should always search for a question like this...right here. https://www.nspn.org/forum/topic/7814-tides-and-currents/
  6. Ah, one of my favorite tomes. Tides and Currents in Portsmouth Harbor, A. J. Hoskinson, US Coast and Geodetic Survey Special Publication No. 150, 1929 https://babel.hathitrust.org/cgi/pt?id=uc1.$b72168;view=1up;seq=5 Should be at https://library.noaa.gov/Collections/Digital-Collections/USCGS-Special-Pubs , but the links from there aren't working now. There are similar pubs for other areas, all about as old. Thanks for finding those tide tables. Hadn't found that before, and it's just what I need for something right now...
  7. You’ve captured it perfectly.
  8. I am. Think of it as an independent study project for the jobless.
  9. Waves, tides, and currents: the kayaking environment Sunday, February 17 - 11 am to mid afternoon - REI Community Room, Reading MA We’ll learn the physical causes of waves, tides, and currents, and might find out: Why do waves come in sets? Why are the waves on some beaches always dumping? Rip current…friend or foe? Why is the water so rough around headlands? Why does a 12 second wave have 4x the energy of a 6 second wave? Why is the tide 50 minutes later each day? Why is there a bigger and a smaller tide each day…sometimes? Why are the tides so big in the Bay of Fundy? Lots of drawings and graphs, few equations (all avoidable). After the presentation we’ll have an open discussion of strategies to deal with waves and currents as a kayaker, where to get predictions, and rules for interpolation. This event is open to paid club members only. Please RSVP on the club calendar here.

    Charts

    Jim, More discussion on this in a previous topic, Don't forget to add a scale and lat/long. I got tired of paying Staples for lamination (already have a 11x17 printer), and got a cheap Amazon Basics laminator, about $30. Works great. A pack of 100 laminating sheets costs more than the gadget, but maybe people could get together and split a pack.

    2019 Pool Sessions

    Keith, In theory it should be, however... ACA is still working out some of its membership practices, and we're still working out how to deal with them. I don't see you listed with ACA as a member of NSPN as a PAC. A paper waiver (with your ACA member number) would help, at least for now. Thanks, Mike
