   This script really reaffirmed for me that he understands what film can be as an artistic medium. The ideas behind the story manifest in every aspect - theme, structure, music, and I would assume visuals, if he ever got to make it. The music does really help set the mood. Grand but grounded. Beth's theme, Dime Shaped Mass, is my favorite.

   Is the Southern Ocean a 'iron-limited' ocean?

   • The Southern Ocean, where Martin developed his hypothesis, is one of the most “iron-limited” oceans in the world. Even with an abundance of other crucial nutrients such as nitrogen and phosphorus, it’s the availability of iron that matters for diatoms and other organisms. Unless, of course, a gust of wind delivers a plume of iron particles.

   Why did oceanographers study iron?

   • Oceanographers first became interested in iron in the 1930s, hoping to explain why the major nutrient inventories (nitrogen and phosphorus) were not fully depleted by primary producers in surface waters of much of the Southern Ocean 2, 3, 4 (the ‘Antarctic paradox’).

   What type of iron is found in the ocean without oxygen?

   • Oxygen prefers to form compounds with a particular form of iron called “ferric iron” or “iron ( III ).” In an ocean without much oxygen, ferric iron precipitates as iron oxide. This iron ( III) oxide falls to the ground and becomes incorporated in rock while another form, ferrous iron or iron (II), mostly stays in the water.

   What if iron landed in the Southern Ocean?

   • When this dust landed in the iron-starved Southern Ocean, Martin argued, the iron within it would have fertilized massive blooms of diatoms and other phytoplankton. Single-celled algae with intricate silica shells, diatoms photosynthesize, pulling carbon from the atmosphere and transforming it to sugar to fuel their growth.

   the first iron man was the best Iron man, it was well paced and its music made it even better. The Semi-cold/morbid opening made it all that much better and shocking when i watched it for the first time. only the ending fight was underwhelming, but it was followed by a pretty good concluding scene that felt very appropriate for RDJ Iron man.

   Iron fertilization is a Carbon Dioxide Removal (CDR) technique that would mimic this natural system, artificially adding iron to the ocean’s surface to stimulate growth of phytoplankton. The oceans are often naturally fertilized by dust storms like this one in 2003, which covered a vast swath of the Atlantic Ocean with a plume of iron-rich ...

   Apr 27, 2005 · Oxygen reacts with many metal ions, including iron. The formation of rocks from iron in ocean water and the absorption of iron from rock into ocean water is called iron cycling and is important to life, since cells need iron to live. A team led by NASA Astrobiology Institute investigators hypothesized that the oxygen content in the ocean ...
