Dating Lava Flows on Mauna Loa Volcano, Hawaii
For hundreds of thousands of years, lava flows have created intricate patterns on the slopes of Hawaiʻi's Mauna Loa volcano. Until the mid-1970s, it was impossible to know when each of the flows occurred. However, as this video segment adapted from NOVA describes, scientists are now using tiny artifacts of life encased in hardened lava flows to piece together the mountain's complex geological and biological history. Closed captioning included.  Run time 04:36.

17.952 Great Power Military Intervention (MIT)
The purpose of this seminar is to examine systematically, and comparatively, great and middle power military interventions into civil wars during the 1990's. These civil wars were high on the policy agenda of western states during the 1990's. Yet, these interventions were usually not motivated by obvious classical vital interests. Given the extraordinary security enjoyed by the great and middle powers of the west in the Cold War's aftermath, these activities are puzzling.

2.5 Air circulation

At this stage, air circulation enters and plays a dual role. Firstly, winds transmit moisture horizontally from one location to another. In this way, moisture derived from oceanic evaporation can be transported many miles to a land mass. Secondly, convective or vertical currents arising from unequal heating or cooling can transmit moisture upwards. When it cools, some of the water vapour condenses. It is from these currents that most precipitation develops.

2.1 Effects on primary producers in freshwater ecosystems

Plant species differ in their ability to compete as nutrient availability increases. Some floating and submerged macrophyte species are restricted to nutrient-poor waters, while others are typical of nutrient-rich sites (see Table 2.2). Figure 2.2 shows turbid water in a polluted drainage ditch associated with localized growth of algae. There are no aquatic plants present.
