This map below from pnwscuba.com seems to be the one everyone refers to now. I think, however, there are now two white buoy's with red stripes. Is that right? Has anything else changed? (I think the rope path from the white buoy may now go not only toward the non-intact Honey Bear but also the other...

Correction: I meant to share a link to the full set of pictures from Sunday (not just the first, somewhat fuzzy one). Here is the better link: https://www.facebook.com/ckadie/media_s ... 092&type=3

Joanna, I use a GoPro without lights, but with a filter. Underwater, it is super simple: Push one button and it starts taking pictures. A few seconds later, push that button again and it stops. It gives me snapshot-quality photos, not magazine-quality. Back at home, I use my computer grab the best p...

A page on the Oregon Department of Fish and Wildlife web site says: Crab reproduction Dungeness crab can only successfully mate when the female is newly molted. For this reason, in early spring, adult male crabs seek female crabs that are likely to molt soon. Crabs will stay in this “pre-mating embr...

I have two crab related questions. Yesterday at Alki, we saw a "normal" crab (Dungeness?) scuttle away. We think it was carrying another crab -- same type, a little smaller, inverted. Is this likely? (sorry, no picture) We also saw these two Kelp Crab (?) "fighting". Is that righ...

I have always thought that it was coralline algae Thanks! Looking it up ( Bing: 'coralline algrae encrusting' ), I'm sure that's right. The articles talk about its ecological importance. More people want to grow it (mostly in salt water aquariums) than want to remove it. (I hope I didn't hurt its f...

YellowEye, Thanks for the clarifying question. I'm mostly curious about the pink/purple stuff. From Internet searching (that mostly hit swimming pool forums), I wonder if it is "pink algae", which is actually a bacteria (perhaps even a cyanobacteria). I find it interesting that it grows so...

Thanks! I've never seen a lingcod there, but we saw two egg masses this morning.

I'm wondering if the slime is some creature's glue and it just doesn't stick well to fiberglass.

Anybody know what this slime is from? It's on a fiberglass box at Alki Cove II. We saw these Styrofoam-like eggs (?I assume) in the end of a log/pier. What creature might have laid them? These are pictures from this morning.

Thanks!

Aside: The article on Vancouver dives says: Howe Sound is essentially bottomless, plunging approximately 700-800 feet into North America’s southernmost fjord Amusingly, the last time I checked, Wikipedia claimed that both Howe Sound and the Hood Canal are North America’s southernmost fjord. - Carl

If anyone knows Dr. Wallner or sons, please let them know that there is still interest in their book. It would be wonderful if they would re-publish it as an ebook (or just a free PDF).

Thanks! Here is a 2-minute video version:
(I just had YouTube stabilize the video which added some amusing artifacts: shaky, cutoff titles and motion blur now looks like out-of-focus blur)

Last Tuesday, after some reassurance from NWDiveClub about visibility and wind, I ditch work and we go diving. Our goal: to explore near the Lopez Pontoon. We saw this area very briefly at the end of our last dive, two weeks ago. This dive, we surface swim (and swim and swim) to the south most blue ...

Thanks & thanks! We are planning on diving tomorrow (Tuesday). Now, I'm hoping the winds -- predicted to be 9 mph from the S at Noon -- won't be cause too much surf.

We'd love to dive Edmonds tomorrow. The exchanges will be great. The latest weather reports look good.

But will today's heavy rain mean bad viz everywhere tomorrow?

(I don't have a good understanding of how predictably rain one day effects viz the next.)

I'm trying to understand buoyancy and played with this calculator, http://www.divebuddy.com/calculator/weight.aspx. Here is what I observe with respect to Northwest drysuit diving for a 175 lbs diver. Does this ring true? Going from Steel 100 to Steel 80 would lightens weights by 2 lbs (+ the weight...

ScubaJess, Thanks! Our favorite part of the trip was two tanks of daylight cavern diving. I posted pictures to the Photo&Video forum a couple of days ago: http://www.nwdiveclub.com/viewtopic.php?f=14&t=23981 All these saltwater pictures were taken with a GoPro Hero4, natural light with a red...

At the end of January, we did five salt water dives at Puerto Aventuras, Mexico. We dive, with a guide (and usually other divers) from little boats into reefs 5 or 10 minutes from the dive shop. On one dive, we follow this giant sea turtle. http://slugco.com/meta/GoProScuba/boat/Turtle4_small.jpg Di...

Here are pictures from a two dives with Dive Aventuras in Puerto Aventuras, Mexico. We returned two weeks ago. http://www.diveaventuras.com/ The meteor that (likely) killed the dinosaurs 66 million years ago also formed the Yucatán Peninsula. The Yucatán is a pancake of limestone only 30 or 40 ft ab...

Jan,

I loved the article about you and with your photos in Pacific Northwest Diver.

Does anyone like skins? Are they good for helping get the wetsuit on? (Is something else better? baby shampoo? It seems like the answer is always "baby shampoo")

Greetings, All the inexpensive dive skins we see are one piece. Wouldn't two piece be more convenient? Can any one suggest two piece sets that aren't $100 per piece? More Details: We think we want dive skins to go under our 5mm wetsuits (for ease of entry and a little warmth, for Playa del Carmen Me...

I've made a YouTube tutorial about how to take snap-shot quality stills pictures with a GoPro Hero4 (with no lights). https://www.youtube.com/watch?v=54bwE5N7G_c David Newman of GoPro was kind enough of sanity check the method. I recommend 2.7K resolution, but he suggests going all the up to 4K beca...

Hi, I'm trying to gauge interest in a better write up (and maybe a YouTube tutorial). For divers who don't want the hassle of lights, do you think the Hero4 offers something new? Are there other under-$500 cameras with ISO 6400 (which I think is what allows the 1/30 sec shutter under 40' of green wa...
