Fertilizing the Ocean with Iron


Interesting experiment. With so many fishes turning up dead in the oceans in the last few years, it makes you wonder if it is not related with some of these experiments.

Unresolved Questions
Twelve small experiments have shown that blooms of phytoplankton consistently result from intentional addition of iron to the ocean. But the efficacy and ecological impacts of iron fertilization remain uncertain, particularly with larger-scale experiments. If and when a new round of experiments is begun, these questions will be first on the list:

  • How long will carbon be sequestered in the ocean?
  • How deep is deep enough to accomplish this?
  • How can sequestration efficiency be increased?
  • How does the ocean food web change during and after a bloom?
  • Which phytoplankton and grazers raise sequestration efficiency?
  • Which parts of the ocean are best for iron fertilization?
  • What size and what shaped patch should be fertilized?
  • How often and how continually should iron be added?
  • What kinds of currents and surface conditions give the best results?
  • How can the amount and fate of carbon from a bloom be verified?
  • How could effects downstream of experiments be detected?
  • How could the production of other greenhouse gases be monitored

Lack


Saturday
Day off. Short bike ride.

Sunday
Nice hilly run from Oakwood Valley trail, up to Miwok trail and back down through Old Springs trail to finish the loop. My legs were feeling tired before the run but I managed well the steep hills.

Monday
I ran three times the Oakwood Valley trail loop. The weather was perfect after an night and morning rain. Nice and cool. I started slow and gradually increased the pace.

Tuesday
My run was seven times the China Camp loop. I started slowly and gradually increased the pace. By the last loop I was almost speeding. 

Wednesday
Day off. Short bike ride and upper body weights.

Thursday
I ran from home to the Ten beach and back. Some good hills. My legs felt good. Nice cool weather after a morning rain. Total run time: approximately 1 hour and 20 minutes. Short bike ride and upper body weights.

Friday
Nice run after a hard working day. I ran five times the China Camp loop at a fast tempo pace. I felt good. I was planning to run the loop seven times but I started to have some stomach problems. To finish my run I ran ten times this short steep hill, walking down in between repetitions.

Common Purpose Exposed

Puff


Saturday
I left home around 4:30 PM in direction to the bike path, choosing the long steep climb of 3/4 miles that ends by the local high school. From there I crossed the street and made right on the bike path. I ran to its end by the bike shop and turned around, passing the starting point and running all the way to the other end by the local nursery and back to the start point where I got off the bike path and ran back taking the same route. I ran a little faster than I should but my legs felt strong. Total run time: 54 minutes and 16 seconds.

Sunday
day off.

Monday
Good run on the China Camp area. Same 3/4 miles loop as last week. I ran seven times the loop around 2PM. This loop might be short than 3/4 miles, more like 0.70 miles. Hot weather. I was feeling tired after work. Short bike ride. Total run time: 29 minutes and 16 seconds.

Tuesday
I ran late in the evening after a short bike ride. It was complete darkness when I started doing my laps around this soccer field. Nice soft grass surface. My watch battery went dead. I could not see a thing in the dark, but I did not have any accidents. Maybe I ran around fifteen laps. I lost my sense of time or laps. I was just trying to avoid falling on my arse.

Wednesday
Day off.

Thursday
Hard run on the hot weather. I ran six times the Oakwood Valley trail loop. My run started around 12:30PM. The weather started to become uncomfortable around 1PM. By the fifth loop my legs started to feel a little trashed. I managed to finish my run strong. I added a few minutes on the road as a cool down. 

Friday
Easy short run for half way on the bike path. Fast pace. I was not feeling well during the day so I decided to do my run around 6PM. Short bike ride.

More



Saturday
Three times the Oakwood Valley trail loop.(9:43; 9:10; 8:55) I am back running this loop under nine minutes.  My  legs are feeling better. Total run time: 27 minutes and 50 seconds.

Sunday
I ran from home to the bike path and back. Fast going up the initial long steep hill. I kept a good pace on the bike path, and slowed down the way back. Total run time: 47 minutes.

Monday
Day off.

Tuesday
Back to China camp where I did a short speed session. I ran nine times the 3/4 miles loop including two times as warm up and two times as cool down. My speed session consisted 8 x  1 min hard, 1 min easy. Total run time: 39 minutes and 30 seconds.

Wednesday
Day off. Short bike ride.

Thursday
Good run on the bike path. I rode my bike down to the bike path and ran the bike path course out and back and  around the soccer fields. I felt good. Total run time: 44 minutes.

Friday
Another good run. I ran the usual bike path, out and back course. My goal was to run the first half in eighteen minutes. It turned out faster than that, 17:53. (9:01; 8:51) I ran the second half in an easy pace. Total run time: 30 minutes and 3 seconds.

Sub




My week was weak.  Sometimes other priorities take over your life. Right now I am just trying to stay fit at a minimal effort. My speed is improving as I ran more often on the Oakwood Valley trail. I am way behind with my endurance. I need to have my long run of at least ninety minutes every week to improve my endurance

Saturday
Day off.

Sunday
Easy short run around the soccer fields. Twice the loop with some short steep hills. Hot weather. Total run time: 29 minutes and 37 seconds.

Monday
Day off. Long working day. Very hot day.

Tuesday
Day off. Very hot day. Short bike ride.

Wednesday
Good run. Back to China camp. Hilly course. I ran in the middle of day, hot weather. Total run time: 52 minutes.

Thursday
Day off.

Friday
Back to the Oakwood Valley trail. I ran three times the loop. (10:13; 9:32; 9:11) My legs felt good. Total run time: 28:57.
