Is our blue marble turning green? (8/4/2016)

"Far above the world, Planet Earth is blue, and there's nothing I can do" 

- David Bowie -

This was the view from our cockpit the other morning watching the sun come up over the horizon during an early morning sail on the Chesapeake Bay.  The water in the Bay this winter was remarkably clean and clear.

But here on earth there is a lot we can do to keep that water blue and healthy.  Although it seems to get more and more difficult.  This week's newspaper reported that the drinking water in our area stinks and tastes bad.  Our water works blames the hot weather and the algae bloom in the lakes that supply our water.  It seems that the algae give the water a bad taste and smell.

The next questions hot weather and algae bloom, what can we do about that?

By now we should have all heard about global warming; it is real and there is probably not much we can do about in the short term.  But in the long term, yes we can.  We need to get serious about energy efficiency and renewable energy; it is not only good for the planet, but also good for our pockets.  But yes it is an expensive investment in the short term and the returns are slow to materialize (it will pay you back in so many years).  For example, we are saving $15.00 every two months on our water bill since we installed two $180 low flow toilets.  This means it will take us 48 months or 4 years to break even.

The hot weather has warmed up that wonderful nutrient rich water and made it the perfect breeding ground for all those algae.  Note the words nutrient rich!  How does the water get nutrient rich?  Oh yes, blame those farmers!  Well, not so fast.  We are to blame as well.  We over-fertilize our yards, or put fertilizer where it does not belong; people don't pick up after their animals; don't maintain their septic systems; dump their fall leaves in a ditch or in the woods where they don't belong; wash their car in the street and not on the lawn or at a car wash; or poor chemicals down the storm drain.  All that stuff eventually ends up in the streams and rivers where we all get our drinking water from or that end up in the Bay.  And the algae love it!  Look for the word eutrophication that's what scientist call it.  It means enriching the water with nutrients.

Last September we went on an evening sailing trip to watch the algae at night in their phosphorescent state.  It was quite the adventure and I wrote about it in this blog posting.  Who knows, I promised a few friends to take them out if it happens again, and I secretly hope it does not, although I love to sail at night.

But lets get back to the question, is our blue marble turning green?  The earth was first called blue marble by the space program on December 7, 1972, by the Apollo 17 astronauts when they took a picture of the earth on their return trip from the moon.  Subsequently, other satellites that flew much further from earth also looked back home and took pictures of the blue marble floating in space.  (I learned about this term from Wallace Nichols' book "Blue Mind" he actually started the Blue Marble Project). 

This is a copy of the original photograph taken by the Apollo 17 astronauts.   Picture was downloaded from NASA.

My question is with global warming and eutrophication, will the blue marble stay blue or will it turn the oceans green with algae, or will it turn the world green with people who think green and want to help save and protect the environment?  

That choice is ours isn't it?

Evening sail on the Chesapeake Bay (8/22/2015)

We had a great and interesting evening of sailing this past Saturday.  We took our daughter and significant other sailing in the area where the York River enters the lower Chesapeake Bay.  We had a couple of firsts and it was an interesting time.  Sara, our daughter’s girlfriend had never sailed in her life, so that was a first.  The week before there were reports in the newspaper about major algae blooms causing gorgeous bioluminescent events on the river.  The photographs in the newspaper were spectacular.  We had seen the same thing during the meteor shower when my wife and I walked along the York in the evening and aquamarine waves were crashing into the shore that night and we hoped we could replicate something similar for our guests. 

So we decided to make it an evening sail in the hope the algae were still going strong.  We made chicken-humus-spinach-sprout wraps for dinner and armed with some snacks and drinks we set sail at around 5 pm.  The wind was from the north at 10 to 12 knots.

Well, 10 to 12 knots does not sound too much, but coming from the north is fun sailing especially in the southern Bay.  Typically waves are the highest when the wind is from the north and northeast.  With wind from that direction, the waves do not encounter land for a long stretch and are able to build (this is also known as fetch); and even with just 10 knot wind the waves can easily build to 2 feet in height.  Maybe no big deal, but especially when it is dark you cannot see the few extra-large wave that sneak in from time to time; both my wife and Sara were surprised one of them and got thrown around and were slightly hurt and definitively shaken up.

But let’s start with the beginning.  We started out with a somewhat bad omen.  The head sail (jib) went up great, and when it came to raising the main, I had forgotten to connect the halyard to the main.  So I had to get on the cabin to connect the halyard.  A little screw up, no big deal.  Somehow, the main did not want to go up all the way, whatever I tried.  It was stuck, this dummy did not put on his sailing gloves and I am still bothered by a blister on my finger from trying to pull the main up.  Oh well, it might not have looked that pretty, but the boat sailed and I was not going to let it ruin our evening.  I just lowered the boom a bit and it worked.  Next problem, I was not able to pivot the outboard out of the water, oh well again, in hindsight, even with our little sea anchor we still averaged 4.5 knots over the ground that evening.

We were flying, but boy it shows that, now I have all the windows in, I need to pressure wash the boat.  Also the headsail is a little dirty, but there is little I can do about that, I understand.

About hour into our sail, “BANG”, and the boom flies down wind.  The shackle that holds the mainsheet block attached to the boom snapped.  What to do?  Start the motor.  Time to take the vang apart, and use the block and the shackle from the vang.  So while the crew holding on to the boom, I tried to get everything rigged up.  Here comes one of those larger waves and the pin goes overboard.  So let’s try the other end of the vang.  I am able to get that one installed without any additional incidents and we are off sailing again.

After the repair.  The admiral and me with the new block and shackle from the vang.

In the meantime the sky is getting absolutely gorgeous.  We are all clicking away, cell phones, go-pros, Olympus T-3, you name it.  After having dinner it was getting dark and it was time to get the lights up.  We still do not have electricity on out boat, so I bought a set of battery operated navigation lights.  Somehow I had not put them up before we left, so I gave the helm to my wife and crawled up front (without life preserver and two to three foot seas) to put the thing up.  Well, a screw came lose.  Miraculously, I was able to catch it but I needed to crawl back to get a screw driver and fasten it again.  Then crawl back to the front and attach it.  Finally back in the cockpit I checked the GPS for our position and had the shock of my life.  Because of all the time it had taken me to get the navigation lights up on the bow, we had gone too far and actually crossed an area that we usually would avoid at all cost.  The area we crossed has a sand bar with a depth of 4 to 6 feet and our boat draws 4 feet and having no electricity we have no depth finder.  Thanks goodness it was mid-tide, but with two foot seas, we could have hit bottom at the bottom of the waves.  With me up on the bow, trying to attach navigation lights, that would have been very interesting.  Nothing happened, but we learned an important lesson: situational awareness; make sure you know where you are and that you need to have enough wiggle room just in case you need it especially when working on something!

The sun is about to set in the west.

A nice head wind, waiting for darkness and the algae glow.

Shutterbugs.

The rest of the evening went great!  After it got completely dark the light show started.  The sail was absolutely spectacular.  Black seas with aquamarine streaks (the crest of the waves), and an aquamarine wake from the boat sometimes bright enough you could read a newspaper by.  Unbelievable.

The algae that are causing the bloom are Alexandrium monilatum.  The algae is somewhat toxic; not horribly toxic to humans, but this species does appear to be toxic to young fish, young oysters and young crab.  Older ones seem to be able to withstand it.  While the bioluminescence is a sight to behold, it is also an indication of too much pollution in the water.  The algae bloom are caused by the pollutants we generate on land and that runs off in our stormwater, in particular phosphorus and nitrogen in animal waste and fertilizer.  An interesting juxtaposition, my hobby (sailing) and my profession (sttormwater education), all together.

Yorktown beach (6/26/2013)

Tidal flat at low tide.  After dinner we took the dogs for a walk on the beach.  I was struck by the algae on the rocks at low tide.
