On trainers and teaching, Part VI, what walls? (11/25/2015)

It is always interesting to see that when you start something it has unforeseen consequences, in particular when they are positive.  Call it serendipity or coincidence, but it is often not the intent.  In my case, it brought down a few walls, or boundaries.

So what am I talking about?  As I recently mentioned in a post I was developing a course on wetlands and how it relates to stormwater and erosion and sediment control.  We felt there was a tremendous need for a class like this, since we always talk about wetlands in our classes and the need to avoid impacting them.  We felt that I was the person to do this because I have worked as a wetland scientist throughout the U.S.A. since the early 1990-s.  Well, we have rolled out the class and given it at two locations.  The class has been well received and the evaluations are great.  Both the materials and the teacher (me) are well liked.  So there is something to say for being multifarious, a jack of all trades, it helps in thinking things through in developing a class and standing in front of a room and talking about a subject.  I discussed that in this post as well.

A tidal salt marsh in a creek that is a tributary to the York River.  Tidal marshes are really interesting, to the eye they may seem fairly uniform and only occupied by a single species.  But this is far from the truth.  During high tide they are teaming with small (young fish) and at low tide they have fiddler crabs and other critters.  The plant species in them have a very narrow tollerance range of water (tidal) depth.  It is a really neat system.

Why then the unforeseen consequences?  That for a big part may have to do with my personality.  While I love to teach and be in front of a class; I hate to practice, do dry runs of my classes, tell people how it goes, what I am doing, you know it.  I find it difficult to develop outlines of what I am doing or how the class will go (a waste of time almost, I rather be developing the class or think about it).  For me developing a class is an organic I start out with a few ideas and things go from there I put things before it and behind it, wherever it makes sense in my eyes; I brood.  This can be infuriating to my supervisor, although he has learned to live with it and understands it.  However, you can imagine that people who do not know my style and more vested in the subject matter can get concerned when they experience my style first hand.  I do not like to rehearse my classes, and when I do, I find it difficult to treat a group of my colleagues, who I assume know as much as I do of the subject, as the students I am supposed to teach and know very little.  It feels like I am talking down to them and that is something I cannot do.  I like to talk to people at their level, which is probably why people rate me so high as a teacher (am I too arrogant here? I really don't like talking down to people, unless I don't like them, then I talk down to them like the best of them!).  Moreover, I do not rehearse my classes.  As I tell my students in the first class: “You guys are the dress rehearsal and the main event all at the same time!” 

During the development of the class I’ve felt two or three times that the class would be cancelled because of the sensitive issues that wetlands raise in this country.  We understand more and more about their importance as an ecosystem and habitat that needs to be protected, and for that matter the push back that conservationists have had in the past from the development and home building community.  So it is logical that this class was under somewhat of a microscope to start with.  Moreover, people are protective of their own turf, so it is difficult to have an outsider like me teach a subject that another group in our department is responsible for; they are the experts and they had no idea what my level of expertise was or what my teaching style was.  On top of that was my style of course design and development (in other words don't do as I do when you do course design) and my marginal ability to articulate it.

However, I can report all is well and I have received compliments from the group that considered asking us to cancel the classes and we received an offer from them to co-teach the class with me, the greatest compliment I can get.  I consider it a breaking down of a virtual wall between groups that is there whether you want to admit there is a wall or not.

But one thing is for sure you never get to tear down walls or get these neat unforeseen consequences if you don't try!

And yes, I need to really try to be more transparent in my course design, I guess.

Virginia Beach (6/9/2015)

What a difference a decade makes.  I was at this location more than a decade ago to do an environmental inventory, and it was a contaminated site that needed some serious work.  Development was encroaching and there was a tremendous pressure to do something with the site.  I'm so happy to be here now and see what the Chesapeake Bay Foundation has done with it.

A view of the Lynnhaven river from the Education Center.  Interestingly, when I got my sailboat five and a half years ago it came out of the inlet in the back.  The boat could not get out at low tide and we had to pull her over a sand bar.  The problem was it could not go under the bridge any other time; the mast was too tall. 

The site now has the Brock Environmental Center and we are giving a stormwater class in their class room.  The building is LEED certified (platinum), they used good environmental site design, recycled materials,  do not use city water, generate the majority of their own electricity and have composting toilets.   Yes, that in the middle of Virginia Beach!

One of the two windmills that are estimated to produce 40% of the electricity for the Center.  Solar cells on the roof generate the rest.

It is pretty impressive,  the building has been designed to take advantage of the environment while still being protective against the elements, in particular global warming, sea level rise, and just increased flooding events.

Looking outside, you can see that the site is surrounded by tidal wetlands and what looks like a salt marsh community.   I can remember that one would not eat oysters coming from the Lynnhaven; the water they grew in was too polluted.  Currently,  Lynnhaven oysters are a delicacy, prized for it's salty, but delicate taste.  So great to see we are making progress in cleaning up the Bay; albeit very slowly and very localized.

Seaford (2/16/2015)

When I was young, in my early 20s, I studied photography and wanted to become a photographer.  One on the most interesting tricks in the darkroom was solarizing your photograph.  You never really knew what the results would be, but it was always fun.  It came down to putting your sheet of paper under the enlarger and exposing it to light, light every picture you print.  Subsequently, the paper would go into the developer and you were not to agitate the liquid.  At one point, while the picture was developing, you would flip on the light for a few seconds, and in essence your picture would turn black.  At least the areas that were light turned dark.  Simply the developing chemical was not exhausted and still worked.  In the darker areas nothing would happen and the used chemicals would bleed over from the dark areas to the lighter areas, resulting in the fine white lines you see with solarisation.  If you wanted a white picture, you could then put another piece of paper on the developed picture and use the paper as a negative.  Naturally you could do the same with film.  You could really never control the process and the outcome was never really predictable for me.  Now in modern days computer algorithms do all the work.  This picture was taken with my phone and I have the computer do all the work.  Still the results are fascinating, if you do not over use it.

This picture was taken at the yacht club.  It has been really cold these past few days and today we are expecting snow.  Evidence of the cold is the freezing of the water in our creek.  The water is saline, and you know it must be cold when an ice sheet forms.  NOAA tells me that saltwater freezes at 28.4 degrees Fahrenheit or -2 Celsius.   Even the solarized picture above shows the ice hanging off the lines that keep the boats in their place.  The picture below shows the ice on the side of one of the piers.  The ice is covering the shoreline as it is deposited by the tides.  Above the ice is the Spartina alterniflora shore.  This plant (smooth cordgrass) lives in the tidal areas on the east coast, and is an invasive weed on the west coast.  This past weekend we had a talk at the yacht club on sea level rise, and this is one of those plants that will be feeling the pinch.  It does not like constant inundation or feet that are too dry. 

York River (1/16/2015)

The York River is very interesting, it is only named the York when the Pamunkey and the Mattaponi come together at West Point.  At this point it becomes a very wide river.  The river has fairly steep slopes and except for some neighborhoods it is fairly undeveloped until you get to Yorktown.  Before Yorktown you have three areas that are owned by the Federal Government and you see signs on shore that tell you to stay away from these areas, or else!  Another stretch of the south shore of the river is a state park (York River State Park).  That's where we visited today.  The photo below was taken from the visitor's center, looking towards the northwest.

These facilities have a kayak launch and you can also rent kayaks if you don't have your own.  There is a great creek that runs through the marsh you can see below.  It has some fun wildlife, in particular a huge population of fiddler crabs.  Today we hiked along the marsh and saw a number of birds including two soaring bald eagles.  The north and west facing slopes of these marshes are spectacular.  I absolutely love the ecology of the area.  It still amazes me to see pretty darn big trees in this area and a dense understory of mountain laurel (yes they do grow here on the coastal plains).  The photograph below was taken near one of the bird watching platforms in the creek (yes this is a great bird watching area).

I assume that the park is across an area where the native American population lives that became a Disney legend. Archaeologists and historians place Pocahontas' village on north shore of the York. How's that for historical significance.  I guess that's why there was this thing in the local newspaper today telling us that some citizens are trying to get an historic and ecological significance designation for the river.  Hopefully this will be successful.
