Collapse

One of the exhibits, we visited during Cultural Programs of the Natural Academy of Sciences’s #NAS_sciart was Brandon Ballengée: Collapse. Collapse is a huge pyramid of specimen jars that contain species from the Gulf of Mexico that are in decline due to the 2010 BP Deepwater Horizon oil spill. It was interesting to be able to see numerous species up close, even if preserved, that I normally would never see. However, it was sad to think that all these species are in decline or at least affected by the Deepwater Horizon oil spill.

Gowanus Canal

Last month while in New York, I spent some time walking around Gowanus Canal because I’m an environmental engineer, and I couldn’t resist an opportunity to visit a body of water, infamous for being incredibly polluted. The Gowanus Canal is a Superfund site due to contamination with polycyclic aromatic hydrocarbons (PAHs), volatile organic contaminants (VOCs), polychlorinated biphenyls (PCBs), pesticides, and metals. However, the Gowanus Canal is also polluted with more ordinary pollutants such as bacteria from untreated wastewater from combined sewer overflow outfalls and other urban pollutants from surface runoff (and possibly illegal outfalls). The area residents are understandably pushing to get the canal cleaned up quickly, and the cleanup is a joint effort between the city, state, and federal government. The area around the canal is an interesting mixture of industrial, art galleries, and up and coming residential. It is actually a nice area. There is a Whole Foods Market next to the canal that has a nice little canal walk on the property, which features signs that say “This is the greenest supermarket in New York State. No smoking, please.” I will take them at their word about being the greenest supermarket, as I did notice solar panels and wind turbines in the parking lot. However I still had to laugh at the irony of the sign. On the bright side, the Gowanus Canal is not so polluted that should someone smoke near it, it is not in danger of catching on fire, like the Cuyahoga River did in 1969. While I was walking along the canal, I spotted a small boat with two people who seemed to be monitoring the water and also two people in a canoe. I guess the canal is safe to canoe on, if you just make sure you don’t touch the water to your skin and most definitely don’t let any get into your mouth, nose, eyes, or any other orifices. The canal does not look that polluted. There are areas with floating trash, but there are very few places where I saw a sheen. When I was there it did not smell either, but evidently especially in summer, it can smell. However, it is a good example of how appearance is not a good way to tell if something is polluted. If you want to read more about the Gowanus Canal, this article in Popular Science is pretty interesting.

Run the Chesapeake Bay Bridge 10K

On November 9, 2014, I ran the inaugural Across the Bay 10k Chesapeake Bay Bridge Run. The point to point course includes 4.35 miles across the bridge, which reaches 186 feet at its peak. The run across the bridge provided amazing views of Chesapeake Bay. As an engineer, I really loved being able to examine the bridge up close at a slower pace than when driving across it. I wore a GoPro Hero 3+ on my head during the race to make a video of the run. I have edited the video to only include the start, bridge portion of the run, and the finish, and I have also sped up the video. My official run time was 1:16:24, and nobody wants to watch a video that long of me running across the bridge. I removed the sound due to a weird noise that was created when I sped up the video. Also, I took a few photos with my iPhone and made a few photos from freeze frames from the GoPro video.

Decipher This Warning Sign

I saw this warning sign today by creek near my office. I know what the sign is trying to warn people against, but the drawings struck me as a little weird. I tweeted the photo out with my interpretation of two of the drawings, and then got some more hilarious interpretations. I have listed them below. Submit a comment with your interpretation if you can do better.

Water warning sign

Water warning sign

1. Person standing above water drinking from glass:

Me: Humans, no standing on top of water.

@Ilovebraaains: No standing on top of bacon

@marginfades: and yet, no admonition for walking on water.

2. Person leaning over water with huge water droplets.

@MGhydro: No crying in the water.

@MGhydro: No crying over bacon! Unless they’re tears of joy!

@fMRI_guy: Caution: Windy. While you are washing your face, your towel may just fly away & you’ll be naked

3. Person swimming

@Swansontea: No punching water while in the prone position

4. Person washing car

@MGhydro: No throwing dog poop over cars.

@fMRI_guy: Don’t use your car as a barrier in a snowball fight. That’s just rude.

5. Dog running above water

Me: Dogs, no swimming on top of the water

6. Hand above water with bottle and banana peel (why is it always a banana peel?)

@MGhydro: No picking up trash from the water.

@fMRI_guy: Also, don’t pick up bottle messages.

Me: No sending messages in bottles

@lockwooddewitt: Garbage and bacon: Gotta keep’em separated

 

Old Montreal

I spent much of my short visit to Montreal just wandering around Old Montreal (Vieux-Montréal). I love old buildings, and Old Montreal certainly has plenty of them. It has lots of charm, cobblestone streets, cafes, and shops. It sits right on the St. Lawrence River, and there is a wonderful linear park that separates the river and its quais (wharfs) from the main part of Old Montreal. It is just a lovely place to visit and walk around.

When an engineer gets to comment on building maintenance

One nice thing about where I work is that we get to fill out surveys about how we like the building we work in and comment on it. I have my doubts about how much they act on the survey results, or how much they pay attention to the comments if an employee bothers to give comments, but hey, it’s a great place to vent. I actually for the most part like my building. It is relatively new and doesn’t have the problems that many older buildings that my employer has has. It is kept clean and and looks nice. One big problem I have with it is the same that I have with almost every other office building: the temperature is set at a temperature that is comfortable for men not women. By about 11 am, once the HVAC has fully gotten the ambient air to the set point (as opposed to earlier in the day when it is ramping up after having been off during the night), the vast majority of women are walking around in sweaters, jackets, or blankets that all of us keep at our desk. [Spoiler: When I rule the world, I will dictate two things. Office buildings will be set at temperatures that are comfortable to women, not men. Also, public restrooms will be designed better. In particular, the stalls will be longer so that women don’t have to climb on the toilet to close the stall door. Truthfully there are many things that need to be improved in public restrooms, most of which I and many other people have covered is this somewhat comical, somewhat serious past blog post.] However, the building I work in has some of the worst plumbing issues I have ever seen, especially for a building that is less than ten years old. Ironically it has LEED certification, but whoever certifies it appears to ignore the obvious water wasting issues it has, as I detail below. I’ve decided to share below the comments I gave in the building survey, not because it will really accomplish anything, just as a way to vent and possibly to serve as a warning why if you let an engineer comment on a building with design and maintenance issues, you may get more than you wanted. Thus, my full comments are as follows.

With all the dual flush toilets, only one flush button actually works. With some toilets it is the half flush button, with some the full flush button. However whether or not the working button is actually whichever button it appears to be is unclear, or if they have possibly all been disabled and all converted to full flush. They constantly run. Almost every time I enter a restroom, I have to push the flush button on at least one toilet to get it to stop running. The restroom auto soap and water sinks are like sink roulette. Which sink will give me soap? Which sink will not continuously squirt soap at me? Which sink will give me water? It takes forever to get repairs done on issues in the pantry/kitchens. It took them two weeks or so to put a new aerator in the sink faucet. A part that can be bought at any time at Home Depot. It is not special. Maintenance blames pantry sink issues on reasons that are not the problem. On numerous occasions, water has come bubbling up from the drain pipes into the sink. Sometimes so much water has bubbled up that the sink has overflowed with disgusting brown wastewater. Then maintenance posts signs saying not to put coffee grounds down the drain as that caused issue. While coffee grounds will cause a sink with a bad garbage disposal to not allow the sink to drain (and putting coffee grounds down the drain is a bad idea), it will not cause water to flow up from pipes below. (I’m a chemical engineer I can prove this with fluid dynamics equations!) There is obviously some issue with the drain pipes below our floor, which any competent plumber or chemical engineer could tell you.

While there was no place to attach photos or videos, below is a photo of the backed up kitchen sink and video of it overflowing.

Winooski

While visiting Burlington, I walked to Winooski, which is just to its north, and wandered around. Winooski is a cute little town that is situated next to Winooski Falls, a rocky area of the Winooski River. They have built a really nice river walk area on one side of the river, so you can walk past the falls and also down to the dam. The town square is also walkable and has a bunch of really good restaurants. [Normally I don’t recommend specific commercial places, but I had dinner at Our House, and I highly recommend it. They have all these really good variations of mac and cheese, and it is just so delicious.] The only bad thing about the town is how fast the traffic goes around the town center, which can make crossing the street difficult.

After visiting the Green Mountain Audubon Center, we visited the Richmond area and also went north of Burlington to the area where the Winooski River flows into Lake Champlain. The area is really pretty, and of course Lake Champlain is gorgeous.

Amtrak Vermonter

I think I have written blog posts before about how much I love traveling my train. I love sitting back and watching the world go by. Train travel also sometimes allows you views you could not get any other way. I recently took the Amtrak Vermonter from Washington, DC to Burlington, VT. The latter part of the trip had wonderful views of the Connecticut River and rural Vermont and New Hampshire. It was a wonderful way to start my trip. Here are a few photos from the trip.

Flying Over Greenland

My flight back home from Iceland flew over the southern tip of Greenland. It was an afternoon flight, and it was an almost cloudless sky. Luckily I had a window seat and my camera at my feet. Actual, it wasn’t luck. I always get a window seat if I can. Also, I trust neither the TSA nor any airline with my camera, so it is always carried on the plane. Greenland is gorgeous from above. Not so sure I want to visit though, maybe, for a short visit sometime. I’ve been to Antarctica, so perhaps I should venture to the arctic also.
