在实验室中，在一系列的浮出-浸没状态下，研究了从大西洋西部（新泽西）海岸的不同垂直高度采集的8种红藻和4种绿色藻类的生长产量。正弦潮汐模拟装置由一个有机玻璃框架组成，该框架通过尼龙线连接到一个旋转轮，由一个电动机驱动，每12小时旋转一次。将玻璃盖玻片上的沉降孢子接种物放置在框架上的6个水平处，每6小时交替地从海水罐中取出和放入海水罐中，随后在每个潮汐周期中进行0、18、37、58、79和100%浸没方案。有一个物种在海岸在自然界中的垂直位置和它的增长能力之间的相关性很小，每个潮汐周期的淹没百分比增加。所有测试的物种生长最好时，连续淹没，即使是那些通常被限制在海岸的自然界中的高架位置。大多数生长良好，在所有的制度，其中有一些淹没每潮汐周期，除了一个sublittoral种（Callithamnion byssoides），其增长急剧下降的百分比暴露在空气中的增加。
The growth yields of 8 species of red and 4 species of green algae, collected from various vertical levels on the western Atlantic (New Jersey) shore, were investigated in a range of emersion‐submersion regimes in the laboratory. The sinusoidal tide‐simulating apparatus consisted of a plexiglass frame connected by a nylon thread to a rotating wheel, powered by an electric motor geared to make one revolution every 12 h. Inocula of settled spores on glass cover‐glasses were placed at 6 levels on the frame and alternately raised out of, and lowered into, a seawater tank every 6 h with consequent subjection to 0, 18, 37, 58, 79, and 100% submergence regimes per tidal cycle. There was little correlation between the vertical position of a species on the shore in nature and its ability to grow as the percentage submergence per tidal cycle increased. All species tested grew best when continuously submerged, even those that are usually restricted to elevated positions on the shore in nature. The majority grew well in all regimes in which there was some submergence per tidal cycle, except for one sublittoral species (Callithamnion byssoides) whose growth decreased sharply as the percentage exposure to the air was increased.
