It’s official- the stream-side channel experiment is over!
After two weeks of sampling, our team completed both rounds of metabolism,
nutrient uptake and nitrogen fixation measurements. These efforts involved 15
people, 300 chamber incubations, and scrubbing biofilm off more than 1,000
tiles. Although it’s a relief to be done with the long days, I’m a bit sad
to see the channel experiment come to an end. What am I supposed to do with
myself now that I don’t have any biofilm to grow or channels to maintain? I
guess I’ll have to take up a hobby (gardening should be similar to growing
biofilm...), and of course analyzing all that data will keep me busy for a
while!<o:p></o:p></div>

The majority of our blogposts give our readers a false sense of weather here in Iceland. Although the climate is mild for the latitude, rainy days are common at our field site. Here is a little dose of reality. Enjoy.<br />

The channels have been running for a whopping 45 days now
(which is basically years in “channel time”), and things have been going great
at the site. The hotpot that was giving us trouble in the beginning has been
stable, which means we have consistent temperature treatments, and our biofilm
has been busy growing under the varying temperature and nutrient treatments.
Heath and I have been busy maintaining the experiment during this time, as well
as collecting samples for our biomass time series. These time series data can
show us differences in biofilm growth rates among the nutrient conditions
(i.e., low-N vs. high-N treatments), as well as whether these nutrient effects
change under different temperature regimes. We won’t have answers until the
samples are processed back at OSU, so for now it’s lots of scrubbing biofilm
off tiles and filtering the samples for transport back to Ohio.</div>

But perhaps most importantly, we’re busy gearing up for
our first round of metabolism, nutrient uptake, and nitrogen-fixation
measurements. This will be a 4-5 day push with the entire team involved in the
sampling efforts. During sampling, we incubate the biofilm in small plastic
chambers, so we’ve spent the last few days ensuring the chambers and equipment
is in working order.</div>

<span style="background-color: white; color: #444444; font-family: 'lucida grande', Arial, Helvetica, sans-serif; font-size: 13px; text-align: justify;">I am back from Iceland, after an ultimately successful trip, despite weather that was often difficult and that postponed the start of our five-day 15N additions to the two cold and two warm streams. The shot above is of everyone sampling food web compartments in Stream 11 during the drip. The sun did come out every now and then! The channel experiment continues to go well too. Here's a shot of our REU student Heath Goertzen and MS student Lyndsie Collis collecting and processing tiles for the biomass accumulation time series. You can just make out the diversity of growth responses that are being driven by differences in temperature and nutrient concentrations. Some tiles are still effectively bare after six weeks, while a thick algal growth is threatening to overtop some channels. Maybe we'll see some interesting temperature-nutrient interactions. Time will tell.</span><br />

<span style="background-color: white; color: #444444; font-family: 'lucida grande', Arial, Helvetica, sans-serif; font-size: 13px; text-align: justify;">This year the weather did a good job delaying the start of the planned simultaneous nitrogen isotope additions to our four focal streams (two warm, two cold), as we cannot start them if the streams are too high. We finally got a forecast for a break in the weather, so Mick and Jon started the drippers yesterday evening (in truly awful weather, as it happened). The good weather has now arrived and all 8 drippers (one for ammonium nitrate and one for 15N-enriched ammonium chloride and potassium nitrate in each stream) were behaving well when we changed the batteries after one day out of the scheduled five days of isotope addition. Fingers crossed that those five days go off without a hitch.</span><br style="color: #444444; font-family: 'lucida grande', Arial, Helvetica, sans-serif; font-size: 13px; text-align: justify;" /><br style="color: #444444; font-family: 'lucida grande', Arial, Helvetica, sans-serif; font-size: 13px; text-align: justify;" /><span style="background-color: white; color: #444444; font-family: 'lucida grande', Arial, Helvetica, sans-serif; font-size: 13px; text-align: justify;">Tomorrow we take our first food web samples from the four streams, followed two days later by comprehensive water sampling for nitrogen concentrations and isotopes.

Typically, most of my time in Hengill is spent running
the side-stream channel experiment, so I rarely get a chance to visit the other
streams that our group studies. However, earlier this month I had the opportunity
to assist with checking the nutrient drippers in the “landscape” streams, which
allowed me venture away from the channel site and see what else Hengill has to
offer.<o:p></o:p></div>

This year we’re adding nitrogen to our four study streams
using a rather elegant dripper system that is controlled entirely by gravity.
It’s essentially the same setup as the drippers we use for the channel
experiment, but slightly modified to fertilize an entire stream as opposed to a
small plastic channel. <o:p></o:p></div>

Although this dripper system maintains a remarkably

occasional refill of the reservoir to maintain the nitrogen supply. Here’s Kate

It was a nice change of pace to hike around the streams
of Hengill’s “other” valley, and a good reminder of the interconnectedness of
the work done with the channels and the landscape streams. We’re all excited to

In it, we describe how our experimental warming of Stream 7 at Hengill by 3.8 degrees C changed the structure of its invertebrate community. Somewhat surprisingly, average body size increased. Across all of Hengill's streams we can obviously find taxa with a wide range in thermal preference. It just happens that many of the invertebrates with higher thermal preference are relatively large-bodied (snails and black flies, for example) and these groups responded strongly to our whole-stream warming manipulation. Conversely, many cold-adapted taxa are quite small (many midges are obvious examples) and these groups declined. These results show that shifts towards lower average body size with warming are not universal, and that the combination of diversity in thermal preference and dispersal ability will dictate how communities reassemble as ecosystems warm in the future. Well done to Dan for all the hard work he put in to reveal these patterns!</span>Jon Bensteadhttp://www.blogger.com/profile/12041092628366465079noreply@blogger.com0tag:blogger.com,1999:blog-8956045939710676885.post-19210940908604070802017-06-13T09:34:00.000-07:002017-06-13T09:34:43.370-07:00Update and Hot Pot <!--[if gte mso 9]><xml>

Hey Everyone! </div>
<div class="MsoNormal">
My name is Heath Goertzen. I’m the undergrad REU student
helping Lyndsie with the channels experiment this year. This blog post
shouldn’t be anything complicated, just a quick update on the project so far
and what we’ve been doing. I’ll also be adding a few pictures, just for
posterity. </div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The channels have been operating quite smoothly
(knock on wood) so most of what we’ve been doing is relatively simple
maintenance and monitoring of channel operation, with some sampling for biomass
along the way. We’ve also been spending some serious time standing over the hot
pot being confused. Here’s a picture of it:</div>

Now, that looks like a normal hot pot. For the first 3 years
of the experiment, I’m told that this hot pot sat at a nice 40 degrees C and
behaved itself. Notice the tragic use of past tense because this year, things have gotten weird. Conditions are
changing day to day (perfect for scientific experiments based on
consistency), so this post will probably be inaccurate by the time you see it.
I’ll still fill you in on some of the more notable conditions we’ve seen.
First, the hot pot got sad. See Lyndsie’s posts below mine for more but
essentially, it wasn’t being a hotpot (more of a refreshing bath, really).
Lyndise bailed it out (see below) and that helped at least get the temps back
up. After that, the hot pot started warming in cycles. This involved it going
from the original consistent temperature of 40 C to a potentially face-scalding
90 degrees C. It also started having cycles of activity that I can only
describe as geyser-esque (note, I have no idea what I’m talking about and this
is pure, blind speculation), wherein levels and temperature would both change
over time (~1000 liters of water and 10 degrees C variability), with peak periods
looking like this.</div>

<div class="MsoNormal">
This conditional behavior caused some of the treatments to get
more temp variation than was allowable, so we tried clearing a channel
between the warm pond and the hot pot. The added inflow solved our level
problem (yes!) but the temperature continued in cycles, which in turn
perpetuated the variability (no!). </div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
We finally blocked the same channel we had
previously cleared (the one leading to the warm pond). It feels a bit like playing a game with three options
wherein you’re probably going to lose no matter what you do, but you’re losing
anyways so you may as well try something. Last I heard, blocking the flow has
made some improvements and the hot pot was looking more consistent! I’d like everyone
reading this to engage in some manner of good luck superstition. Rub a rabbit's foot, I'm serious. At this point
we’ll take all the help we can get in maintaining consistency. Cheers and
thanks for reading!</div>

The temperature treatments are maintaining nice 4C intervals, the water flow through the channels is consistent, and the nutrient drippers are delivering a steady supply of N and P to each channel. Now I just get to sit back, relax, and let my biofilm grow. :)</span><div>

full of both small achievements and some interesting challenges.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br />This summer I will be running our fourth and final
side-stream channel experiment, in which we will investigate the effects of
climate change and nutrient pollution on stream ecosystem processes, such as
carbon fixation and the cycling of associated nutrients. To do this we’ll culture
biofilms in side-stream channels along a temperature gradient of 5C-25C (41F-77F),
while adding N and P at varying concentrations and ratios. This will allow us
to understand if the concentration of a nutrient, or its relative availability
to other nutrients, influences how biofilms and their coupled ecosystem
processes respond to temperature.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br />However, before we can answer these questions the channels
need to be up and running, which is proving more difficult than anticipated.
Although the PIs spent the last two weeks getting the infrastructure in place and securing a constant supply of water to our site, the hot pot that warms our water is refusing to stay hot.
Last year the pool was consistently around 45C; this year it struggles to hit
40C and seems unable to maintain a heat source.</span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: x-small;"><i>If a hot pot doesn't produce hot water, is it really a hot pot?</i></span></span></div>
<div style="text-align: center;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: x-small;"><i>These are the questions that keep me up at night.</i></span></span></div>
<div style="text-align: center;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;">I’m currently testing out a few ideas to get the heat back.
Draining the hot pot completely results in an inflow of warmer water- sometimes
the incoming water is 70C- that’s 158F! However, once the pool refills the
pressure from the water seems to “shut off” the heat vent, and the water begins
to cool. Keeping the water levels lower in the hot pot may therefore help us
maintain a constant supply of hot water. I’ll be keeping an eye on the
temperature in the coming days, bailing water as needed, and hoping for the
best.</span><br />

use as the “rocks” in my experiment for the biofilm to grow on. We spent the
afternoon lining the channels with the tiles, and their help sped up the

<span style="font-family: "arial" , "helvetica" , sans-serif;">Recently I travelled to Montana State University to run background water chemistry and nutrient uptake samples from last summer’s side-stream channel experiment in Iceland,

We're seeing how the phosphorus drip affects how fast snails grow in the different temperature streams. We spent the day finding the smallest snails we could.<div class="separator" style="clear: both; text-align: center;">

Running for almost a month now, the tiles in the experimental channels are beginning to show signs of life. The first biomass sampling of the tiles in our light experiment were collected yesterday and Lyndsie and I spent the day scrubbing tiles in the name of science!<br />

Today is Day 19 of the 15N sampling, and the dripper stopped adding the nitrogen isotope on the evening of Day 5, as planned. The worry of contamination is less of a flashing lightbulb now, but we are keeping up the same routines to avoid contaminating our upstream samples with the enriched downstream samples. Jon left on the evening of Day 5, but before we started doing any isotope sampling, he gave a thorough explanation of what to do and what not to do to keep the samples separate.</div>

It was a tough beginning, but the sampling days are spread out now that the dripper is no longer running. Much later, after all this summer business is over, the samples we bring home will be analyzed to measure how much 15N is contained in the different trophic levels so we can get an idea of who's eating who in the food web.

At the end of the day, an additional field season in Hengill means an additional season of wear on the bank where we enter and exit the river. It's looking pretty worn out, so we have been examining possible side routes that will not result in falling back into the river. In the meantime, we've been keeping our boots on when we leave so we can hop out and lighten the load!</div>

Two drippers </span><span style="background-color: white; color: #444444; font-family: 'lucida grande', Arial, Helvetica, sans-serif; font-size: 13px;">adding DIFFERENT stuff to your stream</span><span style="background-color: white; color: #444444; font-family: 'lucida grande', Arial, Helvetica, sans-serif; font-size: 13px;">! Last night Dan Nelson and Jon Benstead started the 15N additions in the four streams along the temperature gradient. So for the next five days each stream will have two drippers going - one adding phosphorus and one adding 15N-enriched nitrogen at tracer levels. Lots of work ahead of us as we follow where all the isotope goes and find out how temperature and phosphorus addition interact to affect nitrogen uptake and routing through the food web. Below is a shot of Stream 11 (our coldest stream), with the phosphorus dripper on the right and metering pump delivering the isotope on the left. </span><br />

It's a beautiful place, and we all take lots of pictures...most of them on days when we don't worry about our cameras getting wet and when we don't mind staying out a bit longer.<br />

Since the Veidi is kind enough to let us store equipment there during the year, we got off pretty light on lab packing this summer:<br />

Once we landed in Reykjavik we met up with St. Kate's tech/lab manager Delor at the airport, then took a bus to Hafnarfjörður, the neighborhood we'll be living in this year. The weather's about 45F with 30mph wind gusts, so we all hunkered down to wait for our ride to the house.<br />

The plan is to spend tomorrow prepping gear at the Veidi, then head out to Hengill on Thursday to do some landscape sampling!</div>
