Abstract: Eighteen samples of Gigartina papillata from relatively high, medium and low tidal heights in the uppermidtidal zone on an exposed section of California coastline were analyzed for total carrageenan content. Results showed an increase in carrageenan content in relation to increasing tidal height. Desiccation and rehydration rates for hich and low samples desiccated more slowly and rehydrated faster than low samples. The difference in carrageenan content is thought to account for this difference.
